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

*- 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
