Question

integrate: sin3(2x)cos(2x)dx from 0 to 8

Answer 1

like this? \[\int\limits_{0}^{8} \sin^3 (2x)\cos(2x)dx\]

Answer 2

yes

Answer 3

u-sub.. let u=sin(2x)

Answer 4

i think i am doing it wrong. but i got 1/32

Answer 5

opps and i mean pi/8...not 8

Answer 6

pi/8 as the upper limit... integral = 1/32 is what i got too..
