Here we will discuss finding sine of any angle, provided the length of the sides of the right triangle. sin . Sin Theta Formula. Other than this, there are some generalized formulas derived using this property: cos 2 = 1 - sin 2 ; cos2 = cos 2 - sin 2 ; cos2 = 2cos 2 - 1; Sample Problems. In trig functions, theta is the input, and the output is the ratio of the sides of a triangle. In other words, it takes the length of the adjacent side (the side next to the angle) and divides it by the length of the hypotenuse (the longest side of a right triangle). An inverse function basically undoes a function. Sin Theta = Cos (90 - Theta) and Cos Theta = Sin (90 - Theta) Basically, there are two ways to convert sine function in terms of cosine function.
