It is one of the shortest meaningful mathematical formula in the category of 4 letter or number family. Please read below info for more detail.
Definition: An algebraic approach
From defining a few general properties of the sine and cosine functions, we can algebraically derive the sine and cosine functions themselves.
First, define the sine and cosine functions to have these properties:
sin x = cos x
cos x = - sin x
sin 0 = 0
cos 0 = 1
