Pls why did u differentiate the 1/2cos4x ?

[mauricecolon]

love your vids but this was very confusing and unclear to me ! maybe it was just a difficult problem

RedPaintedTable See the identity he wrote down at 3:00, in pink? If you distribute the 1/2 over the bracket you get 1/2 + (1/2)cos4x

Regarding @1:00 and @2:40, I wish it was easier to pull these out of my pocket when I needed them. Time to use cue cards to commit more identities to memory.

Should the 1/8(sin4x) be negative? Integ. of cosx = -sinx?
