## Hannah_Ahn 3 years ago prove the identity: \left( sec x - cos x over tan x \right) = sin x I cannot solve it alone! :( It's frustrating. Please help. && thanks for those people who's keep helping me. you guys rock! :-)

$sec(x)-\frac{cos(x)}{tan(x)}$

2. Hannah_Ahn

wait i got this question :)

3. Hannah_Ahn

!!!!!!! :D mammmammaiiaa it's okay :) :) :) ;)

4. imranmeah91

ok then

@imranmeah i think it should be (secx-cosx)/tanx ?
