In this lesson we will look at Evaluating Trigonometric Functions for an Angle, Given a Point on the Angle.

Evaluating Trigonometric Functions for an Unknown Angle, Given a Point on the Angle, Ex 1
This video gives a point that falls on the terminal side of an angle, and uses that to evaluate the trig functions at that angle.
Example:
Find secθ if θ is in the standard position on the coordinate plane and the point (5,6) is on the terminal side of θ.

Evaluating Trigonometric Functions for an Unknown Angle, Given a Point on the Angle, Ex 2
This video gives a point that falls on the terminal side of an angle, and uses that to evaluate the trig functions at that angle.
Example:
Find the values of sinθ and cosθ for the angle θ in the standard position on the coordinate plane with the point (7,-2) on its terminal side.
