Verify the trigonometric identities 1) (sin x + cos x)^2 + (sin x - cos x)^2=2 2) (2 - cos^2 x) / (sin x) = csc x + sin x 3) (cos x-sin^2 x) / (sin x + cos^2 x) = (csc x - tan x) / (sec x + cot x) these are the rest of the instructions: for each of the following problems, verify that the left-hand side of the equation is equal to the right-hand side of the equation. try to simplify the side that is most complex and get it to equal the other side. if you come to a point where you are unable to continue, you may have to start over and simplify the other side instead. show work so i can figure out how to do this problem in the future!
