I looked at the pictures of the math formulas, and I'm totally feel like I've been overwhelmed. I've gotten this far and now I feel like I'm stuck at an *IMPOSSIBLE* roadblock. Help!

Hello! That's ok. Everyone gets stuck at one point in time. Perhaps you should learn Trigonometry, so then you can get a better understanding of things. Here's the link: https://www.khanacademy.org/math/trigonometry Hope this helps! ---Inspirable Learner

i am in 10,00000000000 grade and i know every thing in this worlds and other worlds

Okay? What's General Relativity then?

isnt cosine and sine trigonomitry

Yes they are. They get taught over here in mathematics: https://www.khanacademy.org/math/geometry/hs-geo-trig/hs-geo-trig-ratios-intro/v/basic-trigonometry

Lesson 2: Mathematics of rotation

Start here!

Overview of this lesson

Ready to dive into some more math?

In this lesson we are going to derive a powerful formula which will calculate where any point

(x, y)

goes afterrotation by an angle

θ

about the origin.

The formulas we'll end up with are:

What do I need to know before starting?

To derive the rotation formulas we are going to use the basic trig ratios sine and cosine. If you don't remember these ratios you can click here to watch a video review.

Why does this have to be required? I am not interested, but I have to. I mean,it's a learning experience on how to do all that stuff that Pixar does, but unless you're going to be a Pixar person, what do I need this skill for?
