Question

(1/tan x)+tan x=sec x *csc x I have to prove one side of the equation is equal to the other. This is a proof.

Answer 1

\[\frac{1}{\tan x}+\tan x=\cdots\\
\frac{\cos x}{\sin x}+\frac{\sin x}{\cos x}=\cdots\\
\frac{\cos^2x}{\sin x\cos x}+\frac{\sin^2x}{\sin x\cos x}=\cdots\\
\frac{\cos^2x+\sin^2x}{\sin x\cos x}=\cdots\]
And so on

Answer 2

thanks!
