Solve for O and A : a^2+ b^2= c^2 by Pythagorean’s Theorem. We will prove the next two identities using sin^2 (ϴ) + cos^2 (ϴ) = 1. Divide both sides of the equation by sin^2 (ϴ). This time, divide both sides of the equation by cos2 (ϴ). WebbFrom the unit circle definition, the coordinates of the point M are (cosθ, sinθ). And so, ¯ OC is cosθ and ¯ OS is sinθ. Therefore, OM = √ ¯ OC2 + ¯ OS2 = √cos2θ + sin2θ. Since M lies in the unit circle, OM is the radius of that circle, and by definition, this radius is equal to 1. the house of the devil 2009 legenda
