Sorry, another one. If you could just explain how to split up the cos4x and sin4x, that would be helpful as well! Thank you: cot 2x = (1+cos4x)/sin4x

In your very first step, is it cos(2) * 2x or cos(2*2x), because the latter makes more sense, but in that case the step after that does not ... Oh wait! I got it - becuase it's 2x the x in the Double Angle Formula is TWO x as well. Ah. Thank you!
