Hi all,

I am having some trouble simplifying a term, I have attached an image. How do you get from the first line to the second. If there are any rules please point them out. Thank you.

Hello, dadon!

. . . . . . . . . . . . . .1

We have: . -------------------

. . . . . . . . . . .(1 + tan x)²

. . . . . . . . 1 + -------------

. . . . . . . . . . .(1 - tan x)²

Multiply top and bottom by (1 - tan x)²

. . . (1 - tan x)² . . . . . . . 1 . . . . . . . . . . . . . . (1 - tan x)²

. . . -------------- · -------------------- . = . --------------------------------

. . . (1 - tan x)² . . . . .(1 + tan x)² . . . . (1 - tan x)² + (1 + tan x)²

. . . . . . . . . . . . . 1 + -----------

. . . . . . . . . . . . . . . . (1 - tan x)²
