About Trigonometry Is there anything cool about trigonometry? I was just curious. I'm learning trig right now and I often find myself asking myself, "What's the point?" I feel if I knew what I was working on and why, I'd be more successful and goal-oriented. 

Want to build something with tools? You'll need trig to get the measurements right.
Want to create a game? You'll need trig to understand the math.
Want to work with electronics? You'll need trig to understand all sorts of things
Want to do astronomy? You'll need physics which uses LOTS of trig.
Want to pass high school and get into a college STEM course? You'll need trig.
At its core Trig is pretty simple, and its all about triangles, and how the lengths of sides and the angles work together. From that all the other good stuff emerge, like how circles work , which leads to how sine/cosine waves work, which then gives you magic stuff like the Fourier series which explains how signals work and pretty much all of modern technology.
Don't be put off by all the cos/cos/tan stuff. Its really easy to understand! Its probably the most fun part of maths I can think of, well maybe group theory is, but I think your a few years off that lol. 
Heres the secret sauce: If your teacher gives you something you can't understand. Try asking him to draw an illustration of it.
