Question

Evaluate:

Answer 1

evaluated!

Answer 2

\[\int\limits_{1}^{2} (7 - 2/x + 7/x^3) dx\]

Answer 3

will I find u and du with this problem

Answer 4

This one integrate term by term.

Answer 5

\[7x - 2\ln|x| - 7/4x ^{4}\] evaluated at x = 2 and subtract off what you get when you evaluate at x = 1.

Answer 6

will it better to bring the x on top ex. 2/x to 2x^-1

Answer 7

7x−2ln|x|−7x^-2 /-2
=7x−2ln|x|−7+7/2 x^2

Answer 8

now I am confussed. I am having alot of trouble with these problems. When I look at them I do not know where to start.
I do not know what to do next

Answer 9

Just put the integral sign in fron of each term and integrate term by term. No confusion.

Answer 10

easy to say if you understand it.
where did the -7 come from then +7/2x^2

Answer 11

The last item \[(7 \ x ^{3}) \] is on the bottom. By convention you rewrite it \[7x ^{-3}\]. When you integrate that you would get a negative term.
