Assuming ya meant

to slimplify, we use a variation of the pythagorean identity and a decomposition into the sin and cos
for the pythaogreaon identity

divide both sides by


since

subsitute

recall that

also that cos(x) is an even function and thus cos(-x)=cos(x)
therfore

so we get

decompose them into

and

to get

multiply by

to get

we can furthur simlify to get

the expression simplifies to tan(x)sin(x)
