The way you typed it ....
tan x - sec^2 x / tan x
= tanx - (1/cos^2x)(c0sx/sinx+
= tanx - 1/(sinxcosx)
= tanx - cscxsecx
Perform the addition or subtraction and use the fundamental identities to simplify.
tan x - sec^2 x / tan x
I do not know where to start.

Hannah,
if you continue by substituting sin and cos for the tan,csc and sec functions, you can simplify further. This will be left as an exercise for yourself.
