Ok I don't understand how to do these 3 types of questions.
Please help me understand how to do them. Thanks for your time.
1. Verify the identity (Can only change one side, and end result must equal each other)
2. Sole the equation.
3. Find the exact values of the sine, cosine, and tangent of the angle by using the sum or difference formula.
345 degrees = 300 degrees + 45 degrees
Thanks for any help.
