I couldn't solve this one:
1 + tan x/ 1 + cot x = 1 - tan x/ cot x - 1

Turn the cots into tans. You should be able to show that both sides equal tan(x).
yes.
Yes you can prove it graphically and algebrically
Oops, edited where I should have posted...
Check my edit.
how do i prove it algebraically?
I tried to prove it and got tan but notwhen i used the left side.
(Worried)
You've gotten the left hand side to equal tan.Quote:

If you can show that the right hand side also equals tan, then obviously they're equal.
