Trigonometric Identities
Hi there .
I'm not sure on how to do this question so I wondering if I could get some help . I'd greatly appreciate it :
Create a trigonometric identity that requires at least 3 steps in the solution to prove it is an identity. The identity must also include cosecant, secant or cotangent. Provide solution .
HUGE Thank you in advance .

This isn't as hard as it sounds.
Take something simple like $\displaystyle \sec(x)$
Well $\displaystyle \sec(x)=\frac{1}{\cos(x)}$
And $\displaystyle \sin^2(x)+\cos^2(x)=1$, so $\displaystyle \sec(x)=\frac{1}{\sin^2(x)\cos(x)+\cos^3(x)}$
Take it one more step. :)
