We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry. About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content. For free. For everyone.

For 2nd wave how it came sine angle additional pi/2

I like how at 6:27 the 'i' in the sin is inverted and looks like an exclamation mark (or a factorial if you are a math nerd)

Why phase constant is necessary to define here... And what is phase constant
Anirban Kopty (5 месяцев назад)
I think, Phase is the whole part inside that sine or cosine, and only that tiny part is called phase difference
