DIY TRIG: How to Make a Surveying Tool to Find the Height of Anything
 
01:20:42
Learn how to use cheap or free household items to make a surveying tool to do real life trigonometry. All math is shown. High resolution images: https://imgur.com/gallery/LcEH2. Note: I make a verbal (but not visual) error at around the 18:00 mark: The internal angles of a triangle add to 180-degrees. I wrote it correctly on the paper but my spoken narration was incorrect. Sorry for the mistake. Combine this surveying tool, used to compute height, with the following parallax tool, used to compute distance, to find the distance to and height of objects: https://youtu.be/ECtCir1ApE4.

Wave Period and Frequency
 
04:52
104 - Wave Period and Frequency In this video Paul Andersen explains how the period is the time between wave and the frequency is the number of waves per second. Period is measured in seconds and frequency is measured in Hertz. Wave period and wave frequency are reciprocals of one another. After watching this video you will be able to determine the period (and therefore the frequency) using a position vs. time graph of a wave. Do you speak another language?

Finding the diameter of a circle using Arc Length-Circles-Geometry Help
 
04:11
Geometry Teachers Never Spend Time Trying to Find Materials for Your Lessons Again! Join Our Geometry Teacher Community Today! http://geometrycoach.com/Geometry-Lesson-Plans/?pa=MOOMOOMATH How do you use the arc length of a circle to find the diameter of a circle? We will look at some application problems using sector area and arc length A pie is cut into 6 equal pieces. The arc length of one piece of pie is 5.4 cm. What is the diameter of the pie? So our strategy is to always draw a picture. Let's start by drawing a picture of the pie and assume it is a circular pie. Let's draw 6 equal pieces. If we have 360 degrees divided by into 6 pieces our central angle is going to be 60 degrees. This gives you an idea of what we are working with. What we will do is use a " Proportion Method" to find the circumference, and then use the circumference to calculate diameter. The proportion method it works like this. We take the arc length and put it over the circumference and set it equal to measure of the angle over 360 degrees. So let's plug in what we know. The arc length equals is 5.4 and we don't know circumference which will become x, and angle measure equals 60 degrees. We then cross product1 times x and 6 times 5= 32.4 which equals my circumference. Next we can work backwards to find the diameter. Circumference = Diameter times Pi which is 32.4. So I will take 32.4 and divide it by Pi and I get 10.31 The pie's diameter is 10.31 centimeters. That is how you use the arc length to find diameter of a circle. You may also enjoy...

In the mid-20th century we began launching satellites into space that would help us determine the exact circumference of the Earth: 40,030 km. But over 2000 years earlier, a man in Ancient Greece came up with nearly the exact same figure using just a stick and his brain. -------------------------------------------------- Follow BI Video on Twitter: http://bit.ly/1oS68Zs Follow BI on Facebook: http://bit.ly/1W9Lk0n Read more: http://www.businessinsider.com/ -------------------------------------------------- Business Insider is the fastest growing business news site in the US.

Featuring Dr. Stan Wagon, Professor of Mathematics - Macalester College. There is no better way to get someone's attention than with an assertion that just seems obviously wrong. Math is full of such things. The talk presents several surprising, even shocking, things from elementary mathematics, such as: A square wheel that rolls perfectly smoothly. A device that uses a normal rotating crankshaft to drill perfect square holes. An application of a non-circular wheel to sewage disposal. A shocking cake puzzle. Surprising new formulas for π. Benford's mysterious law of first digits. The Banach-Tarski Paradox, with constructible pieces.

RELATED RATES: Distance between the person and the plane (KristaKingMath)
 
10:29
► My Applications of Derivatives course: https://www.kristakingmath.com/applications-of-derivatives-course Related rates problems are an application of derivatives and implicit differentiation that allow us to figure out how fast one thing is changing in relation to how fast something else is changing. For example, we might be interested in how fast an airplane is traveling compared to how fast the angle between the plane and an observer on the ground is changing. Related rates problems allow us to do that by using implicit differentiation. We'll usually take the derivative of the equation, taking the derivative of every variable with respect to time t. Then we'll plug in for what we know and solve for the value we're interested in. The key to related rates problems is getting the right equation set up. You need to figure out what equation you can write that will include the value you need to solve for. In addition to that, you may have to come up with a second equation that will give you the value for a missing variable that you need to plug into your first equation. ● ● ● GET EXTRA HELP ● ● ● If you could use some extra help with your math class, then check out Krista’s website // http://www.kristakingmath.com ● ● ● CONNECT WITH KRISTA ● ● ● Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;) Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!” So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student—from basic middle school classes to advanced college calculus—figure out what’s going on, understand the important concepts, and pass their classes, once and for all.

Pendulum
 
01:05:00
A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. When released, the restoring force combined with the pendulum's mass causes it to oscillate about the equilibrium position, swinging back and forth. The time for one complete cycle, a left swing and a right swing, is called the period. The period depends on the length of the pendulum, and also to a slight degree on the amplitude, the width of the pendulum's swing. From its discovery in around 1602 by Galileo Galilei, the regular motion of pendulums was used for timekeeping, and was the world's most accurate timekeeping technology until the 1930s. Pendulums are used to regulate pendulum clocks, and are used in scientific instruments such as accelerometers and seismometers. Historically they were used as gravimeters to measure the acceleration of gravity in geophysical surveys, and even as a standard of length. The word 'pendulum' is new Latin, from the Latin pendulus, meaning 'hanging'. This video is targeted to blind users.

When a pendulum is displaced sideways from its resting equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. When released, the restoring force combined with the pendulum's mass causes it to oscillate about the equilibrium position, swinging back and forth. The time for one complete cycle, a left swing and a right swing, is called the period. The period depends on the length of the pendulum and also on the amplitude of the oscillation. However, if the amplitude is small, the period is almost independent of the amplitude. This video targeted to blind users.

Find the following and state their meanings and units. a) dr/dt b)dA/dt c) How fast is the radius changing when the radius is 2 cm and the area is changing at 20p cm2/min #2 Cones:A conical pit is being filled with concrete. The pit has a base radius of 10 cm, and a depth of 30 cm. The pit is being filled so that the height of water rises at 2 cm/sec. Find the following in terms of V and h, (include meaning & units). a) dh/dt b)dV/dt c) How fast is pit being filled at the point in time that the water level is 4cm. #3 Spheres A sphere being inflated at 10ft^3/sec How fast is the radius increasing once the radiums is 4ft ? #4 Ladder: A ladder 13 ft long is sliding down a wall. At the moment the base is 12ft from the wall, the base of the ladder is moving at 5 ft/sec. How fast is the top of the ladder moving at this moment? #5 Boat and Winch: A winch 20 feet above sea level is used to reel in a rope connected to a boat at 2 ft/sec. How fast is the boat moving when the rope is 45 feet in length. Ice Cube: An ice cube melts uniformly at a rate of 27cm3/sec. If the cube retains its perfect form while it is melting, at what rate are the sides shrinking when each side is 3 cm long ? #Inverted conical Tank: water runs out of a conical tank at 7ft^3/min. The tank has a base of 10ft and a depth of 12 ft. How fast is the water level rising when the water is 5ft deep #7 Trapezoidal Trough:The ends of a horizontal water trough is an isoceles trapezoidal prism. The length is 8 feet and the lower base is 4 feet. The upper base is 10 feet and the depth of the trough is 2 feet. If the water level is rising at 3 feet/min, when the depth of the water is 1 foot, how fast is water being poured into the trough? #9 Hot air Balloon:A hot air balloon is rising vertically from a level platform. A range finder 400 feet from the lift point is tracking the hot air balloon. At the moment the angle of elevation of the range finder is 60 degrees , the angle of elevation is increasing at .10 degrees/minute. How fast is the balloon rising at that moment? Consider a sphere of radius 10cm. If the radius changes 0.1cm (a very small amount) how much does the volume change? Water is draining from a cylindrical tank at 3 liters/second. How fast is the surface dropping? Truck A travels east at 40 mi/hr. Truck B travels north at 30 mi/hr. How fast is the distance between the trucks changing 6 minutes later? A particle moves along the curve C ú »" Ä B fi As it reaches $ the pointa b #fl $ fl the y-coordinate is increasing at a rate of 4 cm/sec. How fast is the x-coordinate of the point changing at this instant? 3. Suppose where is a constant and when 4. Two cars start moving from the same point. One travels south at 60 m/hr and the other travels west at 25 m/hr. At what rate is the distance between the cars increasing two hours later? 5. A plane flying horizontally at an altitude of 1 mile and a speed of 500 mph passes over a radar station. Find the rate at which the distance from the plane to the station is increasing when it is 2 miles away from the station. 6. A conical water tower has a height of 12 ft and a radius of 3 ft. Water is pumped into the tank at a rate of 4 ft /min. How fast is $ the water level rising when the water level is 6 ft A man walks along a straight path at a speed of 4 ft/s. A searchlight is located on the ground 20 ft from the path and is kept focused on the man. § §At what rate is the searchlight rotating when the man is 15 ft from the point on the path closest to the searchlight? A police cruiser, approaching a right-angled intersection from the north, is chasing a speeding car that has turned the corner and is now moving straight east. When the cruiser is 0.6 mi north of the intersection and the car is 0.8 mi to the east, the police determine with radar that the distance between them and the car is increasing at 20 mph. If the cruiser is moving at 60 mph at the instant of measurement, what is the speed of the car? The voltage V (volts), current I (amperes), and resistance R (ohms) of an electric circuit like the one shown here are related by the equation V IR. Suppose that V is increasing at the rate of 1 volt sec while I is decreasing at the rate of 13 ampsec. Let t denote time in sec. A trough is 15 ft long and 4 ft across the top as shown in the figure. Its ends are isosceles triangles with height 3 ft. Water runs into the trough at the rate of 2.5 ft3min. How fast is the water level rising when it is 2 ft deep? Sliding Ladder A 13-ft ladder is leaning against a house (see figure) when its base starts to slide away. By the time the base is 12 ft from the house, the base is moving at the rate of 5 ft sec.
