2. 6.5 Trig Functions of an Acute Angle Example: Find the values of all six trig functions and the angle of measure of angle Ɵ, where P(-4, -5) is a point on the terminal side of Ɵ.

3. 6.5 Trig Functions of an Acute Angle What are the formulas for the basic trig values? sin Ɵ = cos Ɵ = tan Ɵ = csc Ɵ = sec Ɵ = cot Ɵ = Given the following, find the measure of Ɵ in both degrees and radians.

4. 6.5 Trig Functions of an Acute Angle Determining Ɵ Given the following, find the measure of Ɵ in both degrees and radians.

5. 6.2 Trig Functions and the Unit Circle Can we do anything else with the trig functions? How can knowing our formulas help us? Think Pythagorean Theorem and the “basic” trigs Proving Formulas! Prove (Show) that: How many different ways can we prove it?
