Webb15 maj 2015 · From the formula for sin(2θ) we have sin2θ = 2sinθcosθ From Pythagoras theorem we have sin2θ+ cos2θ = 1 So sin2θsinθ = (2sinθcosθ)sinθ = 2sin2θcosθ = 2(1 … 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. Latest Math Topics Webbsin(2θ) = cos (θ) sin ( 2 θ) = cos ( θ) Subtract cos(θ) cos ( θ) from both sides of the equation. sin(2θ)−cos(θ) = 0 sin ( 2 θ) - cos ( θ) = 0 Apply the sine double - angle identity. 2sin(θ)cos(θ)−cos(θ) = 0 2 sin ( θ) cos ( θ) - cos ( θ) = 0 Factor cos(θ) cos ( θ) out of 2sin(θ)cos(θ)−cos(θ) 2 sin ( θ) cos ( θ) - cos ( θ).
