When is #sin(x)=\frac{24cos(x)-\sqrt{576cos^2(x)+448}}{14}#?
I have this equation and I'm trying to figure out which values of x make it true:
#sin(x)=\frac{24cos(x)-\sqrt{576cos^2(x)+448}}{14}#
I checked Wolfram-Alpha and it turns out the solution is
#x=2(\pi n + arctan(2))#
for any integer n, but when I try to get that myself I have been having issues. Can anyone provide a solution or some hints?

Explanation:
Rearranging we get,
Squaring both the sides and simplifying, we get
Simplifying this further, we get the reducible quartic equation
