Answer:

If $sin x = 0$ we get $2 (0) (\pm1) = 0$ which is true. so we have a first set of solutions given by

$x= 0; x = \pi$ ;

Else, if $sin x \ne 0$ we can divide both sides by it and we get

$2 cos x = \frac 1 {cos x} \rightarrow 2cos^2x =1 \rightarrow cos^2x =\frac12\\cos x= \pm \frac{\sqrt2}2$

Which gives us a second set of solutions given by $x= \frac{\pi}4;x= \frac{3\pi}4; x= \frac{5\pi}4;x= \frac{7\pi}4$ ;

We can group all solutions (doesn't matter, but it's more elegant!) by writing

$x= k\frac{\pi}4; k\in \{0,1,3,4,5,7\}$
