Trigonometry Identities: cos(2π + x), sin(2π + x), cos(π/2 -x), sin(π/2 -x)
In this video I show some very useful trigonometric identities which basically involve shifting the sine or cosine functions by either 2π or 360 degrees and π/2 or 90 degrees.…

Trigonometry Identities: cos(x +/- y) = cos(x)cos(y) -/+ sin(x)sin(y)
In this video I derive addition and subtraction identities, cos(x+y) and cos(x-y), using the Law of Cosines and the Pythagorean Theorem. This identity is very useful in all of…
