How to solve identity equations

WebUse the fundamental identities to solve trigonometric equations. Express trigonometric expressions in simplest form. Solve trigonometric equations by factoring. Solve trigonometric equations by using the Quadratic Formula. Thales of Miletus (circa 625–547 BC) is known as the founder of geometry. WebThe identity 1 + cot2θ = csc2θ is found by rewriting the left side of the equation in terms of sine and cosine. Prove: 1 + cot2θ = csc2θ 1 + cot2θ = (1 + cos2θ sin2θ) Rewrite the left side. = (sin2θ sin2θ) + (cos2θ sin2θ) Write both terms with the common denominator. = sin2θ + cos2θ sin2θ = 1 sin2θ = csc2θ
