The Tangent Function

The Tangent Function

The tangent function can be generated by connecting a tangent line on the unit circle to the extension of the terminal side of the angle. The distance along the tangent line to the intersection point will determine the height of the tangent function. As you can imagine, there are some places where this intersection is rather difficult (impossible) to draw.
