Evaluating for all six trig functions for a point on the unit circle

The video tutorial covers evaluating trigonometric functions for the angle 3π/4. It begins with an overview of the homework and playlist, followed by locating 3π/4 on the unit circle. The instructor explains how to memorize the unit circle's points and angles, discusses reflections, and calculates trigonometric functions including sine, cosine, tangent, and their reciprocals.

What is the relationship between the coordinates of a point on the unit circle and the sine and cosine of the angle?

Explain how to find the tangent of an angle using its sine and cosine.

How do you rationalize the denominator when calculating cosecant?
