Today’s a holiday, but that doesn’t mean it’s not the time for another math challenge! Solve the following integral:

$I=\int\cos2xcos4xcos8x...cos2^{n}x dx$

It seems all problems are always integration, let’s tackle a different one:

Solve the following equation:

$\frac{(1-2sinx)cosx}{(1+2sinx)(1-sinx)}=\sqrt{3}$

Well, have a nice holiday, everybody! 😉
