OpenStudy (marcelie):

\[\int\limits_{0}^{1} (x-x)^2 dx \]

zepdrix (zepdrix):

Really? This seems sort of trivial :o x-x = 0, ya?

OpenStudy (marcelie):

whoops suppose to be (1-x )^2

zepdrix (zepdrix):

Ah :D

OpenStudy (marcelie):

sorry im kind of lagging on this site :o

OpenStudy (ijlal):

oh haha :P

OpenStudy (marcelie):

ahah yesh :3

zepdrix (zepdrix):

So bust out that handy power rule :D Or I guess you can u-sub if you need to.

OpenStudy (marcelie):

i got 1/3 as a my final result and this book has 2/3 ?

zepdrix (zepdrix):

1/3 seems right... hmm that's strange.

OpenStudy (ijlal):

the answer is 1/3 you are right the book might have some sort of misprinting issues :/

OpenStudy (marcelie):

yeh

OpenStudy (ijlal):

the integral you get is \[\frac{ (x-1)^3 }{ 3 }\] you can check by verifying it apply derivative |dw:1463953208061:dw|
