[math]1/tanx - sec x + 1/tan x + sec x = -2tanx[/math]
I'm having a little difficulty with this
The reciprocal of 1/tan x - sec x is
cos x / sin x - cos
The reciprocal of 1/tax + sec x is
cos x/ sin x + cos
When i add these together
cos x / sin x - cos + cos x / sin x + cos x
i get 2 cos / sin x
which is then 2 cot? so how is it -2tanx
