WebSin is equal to the side opposite the angle that you are conducting the functions on over the hypotenuse which is the longest side in the triangle. Cos is adjacent over hypotenuse. And tan is opposite over adjacent, which means tan is sin/cos. this can be proved with some basic algebra. ( 5 votes) Show more... Hidden a year ago WebDec 20, 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 + cos2θ sin2θ) Rewrite the left side = (sin2θ sin2θ) + (cos2θ sin2θ) Write both terms with a common denominator = sin2θ + cos2θ sin2θ = 1 sin2θ = csc2θ

WebMay 20, 2015 · Whenever sin (theta) = -1, we get cos (theta) = +-sqrt (1-sin^2theta) = 0 and cos (theta)-sin (theta) = 0 - (-1) = 1. sin (theta) = -1 for theta = -pi/2+2npi for all n in ZZ. Putting two cases together, we have solutions when: theta = 2npi for all n in ZZ and when theta = -pi/2 + 2npi for all n in ZZ To make sure that these are the only solutions:
