Trigonometry: A Brief Overview

For those of you who don't know what trigonometry is or how to use it, I have made a tutorial here to help newer Scratchers know what it is and how they can use it in their projects.

I hope those who see it find it helpful and informative, and those who already know trigonometry find it accurate and refreshing.

Re: Trigonometry: A Brief Overview

You mainly focus on right triangles, and don't mention the law of sin and the law of cosine.

However the ones you do mention are probably more important since they focus on right triangles, which are the most commonly used in programming.


Anyway, if you feel like adding them:

Law of Sine: sin(A)/a = Sin(B)/b = sin(C)/c
Law of Cosine: a^2 = (b^2)+(c^2)-(4bc*cos(A) )

"a" is a side and "A" is the angle opposite of that side.

That's all true, but this tutorial focuses on people just learning trigonometry, so I felt sticking with just right triangles to start with would suffice.
