    Post simplifying trigonometry

    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.

    In a rush, don't really have time to explain the rules, hopefully you can follow from my working out. if not, i will explain later--or someone else will

    Hello, dadon!

    . . . . . . . . . . . . . .1
    We have: . -------------------
    . . . . . . . . . . .(1 + tan x)
    . . . . . . . . 1 + -------------
    . . . . . . . . . . .(1 - tan x)



    Multiply top and bottom by (1 - tan x)

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