Question

Need help with a integrate problem

Answer 1

\[\int\limits (x-1) \sqrt{x} dx\]

Answer 2

let u=1-x
du=-du
int(1-u)/udu
=-int1/u-1du
=1-x-ln(1-x)+c

Answer 3

can you explain that a bit more

Answer 4

WHat do you mean?

Answer 5

like how did you get -int(1-u)/udu

Answer 6

that's not right because if you differentiate the result you dont get the original integral

Answer 7

really

Answer 8

recall a(b+c)=ab+ac

Answer 9

\[\int\limits (x \cdot x^\frac{1}{2}-x^\frac{1}{2}) dx\]
can you try from here

Answer 10

yes really. Should go like this.........

\[\int\limits(x \sqrt{x}-\sqrt{x})\]

\[\int\limits x \sqrt{x} - \int\limits \sqrt{x}\]

Answer 11

thats where i was going
