One interesting way using some linear algebra would be to take the 2d rotation matrix that rotates a point (x,y) counter clockwise around the origin. Sine, however, is not symmetrical. Remember that cosine is a symmetrical function about x = 0.

Trigonometric functions, identities, formulas and the sine and cosine laws are presented.

Cos(x y) = cos x cosy sin x sin y. Trigonometric functions of acute angles. Below are some of the most important definitions, identities and formulas in trigonometry. Cos(x y) = cos x cosy sin x sin y.
