WebMar 26, 2016 · In order to find the sine of an angle, you must know the lengths of the opposite side and the hypotenuse. You will always be given the lengths of two sides, but if the two sides aren’t the ones you need to find a certain ratio, you can use the Pythagorean theorem to find the missing one. WebMay 20, 2015 · theta = -pi/2 + 2npi for all n in ZZ. To make sure that these are the only solutions: Starting with cos (theta)-sin (theta)=1, first add sin (theta) to both sides: cos (theta)=sin (theta)+1. Then square both sides: cos^2 (theta)=sin^2 (theta)+2sin (theta)+1. Then use cos^2 (theta)=1-sin^2 (theta) to get: 1-sin^2 (theta)=sin^2 (theta)+2sin ...
