Indicate each step of your process in the “Statement” column. 

A. Identify the problem statement.

B. Correctly use the identities and/or theorems. 

C. Correctly use the algebraic process. 

D. Identify the final statement.   

This is what it should look like

(1-sin^2) tan x = cos^2 tan x

= cos^2 x tan x                      Pythagorean

= cos^2 x (sin x/cos x)       Quotient
