Evaluate the half angle of tangent for 22 5 degrees

Описание к видео Evaluate the half angle of tangent for 22 5 degrees

👉 Learn how to evaluate the Sine of an angle using the half-angle formula. The half-angle formula for Sine is helpful when you need to determine the exact value of function given an angle but cannot use a calculator or the angle is not on the unit circle. To evaluate all we need to do is enter the angle into the formula and simplify. Rationalizing the denominator is not required but often is asked to be performed.
