Chapter 5.8, Problem 83E

Exercises 82-84 will help you prepare for the material covered in the first section of the next chapter The exercises use identities, introduced in Section 5.2 , that enable you to rewrite trigonometric expressions so that they contain only sines and cosines:

$\csc x=\frac{1}{\sin x}$

$\sec x=\frac{1}{\cos x}$

$\tan x=\frac{\sin x}{\cos x}$

$\cot x=\frac{\cos x}{\sin x}$

In Exercises 82-84 i5 rewrite each expression by changing to sines and cosines Then simplify the resulting expression

$\tan x\csc x\cos x$
