If you could help me with these few problems, it'd be a lot of help. Solve for x, 0≤x≤2(pi): sin²(x)-2sin(x)=3 Prove the following identity: tan²x-sin²x=(sin²x)(tan²x) A light ray with a frequency of 5.09 × 1014 hertz traveling in air is incident at an angle of 40.° on an air-water interface as shown. At the interface, part of the ray is refracted as it enters the water and part of the ray is reflected from the interface. Calculate the angle of refraction of the light ray as it enters the water.

I hope you do realize that Facepunch is filled with a bunch of 12 year olds. You'll get better answers on yahoo answer. Oh and sorry, Not that good in AP math

The fuck, I took AP Physics, and got a 4 out of 5 on the exam, and i have no clue how to do that.
This is why I hate rote learning. I'm sure at one point I could answer all those, but now I have no idea how to do it. I have a rough idea but the details are skewed.
I'm learning this right now ironically.
