So one example in my book goes from this step:
Integral of[1/4 + cos2x/2 + 1/4((1+cos4x)/2)] dx
to
= 3/8Integral dx + 1/4integral 2cos2xdx + 1/32integral 4cos4x dx
I am very confused as to why, in the process od destribution, the integral became 3/8intdx as opposed to just int 1/4dx and so forth... Where did that 3/8 come form?
Thank you!
