Sin 2 theta + cos theta
WebbAs per the Pythagorean identity of sin and cos functions, the mathematical relationship between cosine and sine can be written in the following mathematical form. sin 2 θ + cos 2 θ = 1 ∴ cos 2 θ = 1 − sin 2 θ So, it is proved that the square of cosine function is equal to the subtraction of the square of sine function from one.
