You have seen that you can calculate values of the sine function using right triangles formed by a radius of the unit circle. Values of that result in

*θ*and sin

*θ*that correspond to the

*- and*

*-intercepts of the unit circle.*

The central angles that correspond to these “special” values of are

Copy and complete a table like the one below for all special angles between

Degrees | ||||||||

Radians |

Recall that

All of the 'special' values of

Knowing just these two values allows you to easily find the rest.

For Example,
