The way you would approach this (without a calculator) is by using the half angle theorem. The half angle formula goes as follows: tan(a/2) = sin(a)/[1 + cos(a)] We use this theorem because we know off the bat that 22.5 is half of 45 degrees, and 45 degrees is an easy angle for such calculations. So

An indicated method of calculating the value of tan 75: We could consider 75 degrees as the result of the sum between 2 angles: 45 and 30 degrees. tan 75 = tg(45+30)= (tan 45 + tan 30)/[1 - (tan how to hold an alto sax By using a table, you can see that the value 3.732 corresponds to the tangent of a 75-degree angle. This angle is the closest in whole degrees to having a tangent of 3.732. This angle is the closest in whole degrees to having a tangent of 3.732.. How to find ticks on your body
