i have been trying to crack this but i have had no luck. hope someone can help.

$\displaystyle (sin4x + sin2x)/(cos4x+cos2x) = tan3x$

the X varibale is actually (pie), i just could not type it into the window...

Oh yeah and the Latex for

**pi**(not pie lol) is...

the actual question is prove that

$\displaystyle

(sin4A + sin2A)/(cos4A+cos2A) = tan3A
