When I was checking my work, Wolframalpha took my trig work a step further with an identity that no one in my Calculus II class has ever seen, including my teacher.(adsbygoogle = window.adsbygoogle || []).push({});

csc(2x) - cot(2x) = tan(x)

I tried to prove the identity myself and I looked online, but no luck. Please, could someone prove this?
