Sin 2 theta + cos theta
WebbSine and cosine — a.k.a., sin (θ) and cos (θ) — are functions revealing the shape of a right triangle. Looking out from a vertex with angle θ, sin (θ) is the ratio of the opposite side to the hypotenuse, while cos (θ) is the ratio of the adjacent side to the hypotenuse. 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.
