Sine function evaluated on the notable angles Based on the above image, the graph of sine seems to be increasing from {eq}0 {/eq} to {eq}\frac{\pi}{2}, {/eq} which we know is true because of how such function is defined. We draw a unit circle, that is, a circle of radius ...
So we're best off using a separate approximation for the tangent. All of the approximations we'll use generate a valid tangent for angles in the range of 0 to Π/4 (0 to 45 degrees), so once again a range reduction function will translate angles to this set of values. The code abov...
