B Is The Top Point Of The Trig Circle.

Determine the exact value of each of the following without using a calculator. What i have attempted to draw here is a unit circle. And the fact i'm calling it a unit circle means it has a radius of 1.

Write The Expression In Terms Of Common Angles.

Prolong the radius om until it meets the vertical axis at at t. For simple angles like 45 or 60 degrees, you can simply draw a right triangle with a 45 or 60 degree angle and use elementary geometry. We will soon learn how to apply the coordinates of the unit circle to find trigonometric functions, but we want to preface this discussion with a more general definition of the six.
