Question

int[xsinx(cosx)^4]dx from 0 to pi/4.

Is this tabular integration? I'm not sure how to do that if so.. thank you.

Answer 1

Could yo rewrite the problem? BTW, Do you mean definite integration or integration by parts?

Answer 2

sorry, i wrote the problem incorrectly.

Answer 3

\[\int\limits_{0}^{\pi/4}(\theta*\sin(\phi)\cos^4(\phi))d \phi\]

Answer 4

where theta is treated as a constant

Answer 5

okay, so do you know integration by parts?

Answer 6

If this case, u would be sin(tetha) and dv would be cos^4(tetha)

Answer 7

\[\int\limits_{}^{}(udv)=uv-\int\limits_{}^{}v du\]

Answer 8

ok, would i have to do integration by parts multiple times bc of the power to 4?

Answer 9

yes

Answer 10

oooh
