Rishika 6 years ago How to find the sin, cos … 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
WebMar 22, 2016 · (1) Write this as sin θ − sin ( 99 π / 5) = 0, and factor LHS to give 2 cos 1 2 ( θ + 99 π / 5) sin 1 2 ( θ − 99 π / 5) = 0. Thus you have two possible equations of the form cos a = 0 and sin b = 0. These have the solutions a = ( 1 + 2 j) π and π respectively, where are arbitrary integers.
