6-82.

Review the trigonometric Pythagorean identities from Chapter 1 Math Note listed below. Homework Help ✎

sin

^{2}*x*+ cos^{2}*x*= 1

tan^{2}*x*+ 1 = sec^{2}*x*

1 + cot^{2}*x*= csc^{2}*x*Use one of the equations to find a new expression for sin

*x*.Similarly, write a new expression for tan

*x*.Similarly, write a new expression for cot

^{2}*x*.

sin^{2}*x* = 1 − cos^{2}*x*
