WebAlternately, you could use the inverse of one of the SOHCAHTOA functions, in this case the inverse of sine (sin-1)!To find, an angle of a right triangle all that we need to know is the length of two sides! Then use the same SOHCAHTOA ratios -- just in a different fashion See the example below.. Inverse SOHCAHTOA Way WebRemember that cos -1 (x) will give you the angle whose cosine is x The Value of the Inverse Cos of 1 As you can see below, the inverse cos -1 (1) is 0° or, in radian measure, 0 . '1' represents the maximum value of the cosine function. It happens at 0 and then again at 2Π, 4Π, 6Π etc.. (see second graph below.)
