Hi all

Im kind of stuck on where to go with this trig equation:

$\displaystyle 5 sin 3x = 7 cos 3x$

I was thinking maybe divide by $\displaystyle 7 cos 3x $to make it look like $\displaystyle \frac{5 sin 3x}{7 cos 3x}$$\displaystyle = tan x$

Im really stuck on where to go

Any help is greatly appreciated.

Thanks
