Lorentz transformation derivation part 3 | Special relativity | Physics | Khan Academy

Finishing our Lorentz transformation derivation for t'.

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. 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. Forever. #YouCanLearnAnything

Good step by step. Wonder if there is a shorter method.
Wish he would not focus on colors and not use darker ones on dark board'
Just use one bright color (yellow) or even white throughout.

I fast forward the video just to see what he will eventually gets at... he just plays with the two formulae.

Where exactly is this video on Khan Academy, and why can't I find it through the KA Search function? The same often happens with other videos: new content is notified to me on Youtube that I am unable to locate on the Khan Academy website.

from wave's PDE we can get them as well...
