How do you solve a trigonometric equation
WebMay 9, 2024 · The 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 + cos2 sin2) Rewrite the left side = (sin2 sin2) + (cos2 sin2) Write both terms with the common denominator = sin2 + cos2 sin2 = 1 sin2 = csc2 WebSine, Cosine and Tangent. Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle:. For a given angle θ each ratio stays the same no matter how big or small the triangle is. To calculate them: Divide the length of one side by another side
