Question: In Exercises 1-4, verify the identity by converting the left side into sines and cosines. 1. cot2 t / csc t = 1 - sin2

In Exercises 1-4, verify the identity by converting the left side into sines and cosines.
1. cot2 t / csc t = 1 - sin2 t / sin t
2. cos x + sin x tan x = sec x
3. secx cos x = sin x tan x
4. cot x - tan x = sec x(csc x - 2 sin x)
