Question

Integral:

Answer 1

\[\int\limits xe ^{0.2x}\]

Answer 2

Try integration by parts.

Answer 3

integrating by parts I set u=x and dv=e^0.2x

Answer 4

yes

Answer 5

then I should get du=x and v=5e^(0.2x)

Answer 6

du=dx""""

Answer 7

du=1

Answer 8

then I get 5xe^(0.2x)-25e^(0.2x)+C... can somebody check this? :)

Answer 9

\(v=e^{0.2x}/0.2\) not \(5e^{0.2x}\)

Answer 10

Answer 11

you are right friend! i was thinking about something else xD

Answer 12

I guess you have 1/0.2 which is 1/(1/5)=5 :)
