sin(-x) -sinx
cos(-x) cosx
sin^2(x)+cos^2(x) - =1
pythagorean identity
1 + tan^2(x) sec^2(x)
1 + cot^2(x) csc^2(x)
sin(x + y) sin(x)cos(y) + cos(x)sin(y)
sin(x - y) sin(x)cos(y) - cos(x)sin(y)
cos(x + y) cos(x)cos(y) - sin(x)sin(y)
cos(x - y) cos(x)cos(y) + sin(x)sin(y)
tan(x + y) [tan(x) + tan(y) ]/ [1 + tan(x)tan(y)
tan(x - y) [tan(x) - tan(y) ]/ [1 + tan(x)tan(y)
sin(2x) 2sin(x)cos(x)
cos(2x) cos^2(x)-sin^2(x) = 1-2sin^2(x) = 2cos^2(x) - 1
