Sine Function

The figure shows a definition of sine function.
The unit circle is the circle with its center at the origin and a radius of 1. Angle x is formed by rotating OA about the origin to OP. Then the y-coordinate of point P is sin x.

Tangent Function

The figure shows a definition of tangent function.
The unit circle is the circle with its center at the origin and a radius of 1. Angle x is formed by rotating OA about the origin to OP. Point Q is the intersection of line OP and x=1. Then the y-coordinate of point Q is tan x.
