MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped part. Tutorial Exercise Verify the identity. 8 cos2 8 - 8 sin2 8 = 16 cos2 8 - 8 Step 1 The left side is more complicated, so start with it. Use a Pythagorean identity to simplify 8 cos2 B - 8 sin B. 8 cos2 8 - 8 sin2 8 = 8 cos2 8 - 8 1 - Submit Skip (you cannot come back) Need Help? Read It10. [-/1 Points] DETAILS LARPCALC10 5.2.016.
