Can't figure out this question, a little help would be great.
Solve for X, domain: 0<x<2pi
tan4X - tan2X = 0
What i got is that if we use the double angle formula to expand tan2X into
2tanx / 1-tan^2x
the u move it onto the other side and then somehow tan2x is = to tan4X, I'm very confused, please help.
