Basic Trig Identities sin^2 (x) + cos ^2 (x) = 1

Basic Trig Identities sin^2 (x) + cos ^2 (x) = 1 sin(-x) = -sin(x) , cos(-x) = cos(x) , tan(-x) = -tan(x) sin(x + 2Pi) = sin(x), cos(x + 2*Pi) = cos(x), tan(x + Pi) = tan(x) Special values: sin(Pi/3) = sqrt(3)/2 cos(Pi/3) = 1/2 sin(Pi/6) =1/2 cos(Pi/6) = sqrt(3)/2
