I am really confused please help.

Answer 1

I will write down the question

Answer 2

When???

Answer 3

\[\int\limits_{} (xcos(x^3))^2 dx \]

Answer 4

\[\int\limits_{1}^{0} x^2\sqrt{4-3x}dx\]

Answer 5

compute intergrals

Answer 6

\[1/6(x^{3}+\sin(x ^{3}cosx ^{3})\]

Answer 7

its supposed to say sin x cubed times cosine x cubed

Answer 8

looks to be by parts

Answer 9

mmm im even more confused!

Answer 10

\[~~~~~~~~~~~~~v\\+~u~\int v\\-~u'~\int\int v\\+~u'''~\int\int \int v\]

if u is a poly, itsll eventually derive to zero; then you add up the products of each row

Answer 11

this is the rule?

Answer 12

thats a by parts table setup yes

but there may be a simpler method for these

Answer 13

I see. How do i solve my problems? :/
