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! 😉
