Question

Is my answer right? (calculus)

Answer 1

\[\int\limits_{1}^{e}4x \ln x dx\]

I got 4e-4/x-e/2+9/2

Answer 2

Sorry!! Correct my asnwer to I got 4e-(4/e)-(e/2)+(9/2)

Answer 3

every one here but no one say anything

Answer 4

Did you integrate by parts?

Answer 5

did u integrate that as a indefinite as used some property
i used by parts and got the answer as e^2+ 1

Answer 6

or**

Answer 7

Before you do fundamental thereom of calculus, did you get 4xlnx-(4/x)-(1/x^2).

I know I should integrate by parts but by teacher said there was some trick if one of the functions eventually derives down to zero.

Answer 8

\[x²(2\ln x-1)\]

Answer 9

thats what i got after using by parts

Answer 10

and i dont see any complex thing going on here
