Question

A simple integration prob

Answer 1

\[\int\limits_{}^{}(5x ^{3}+9x-4)/(x(x-1)(x ^{2}+4))\]

Answer 2

:)

Answer 3

oh forgot a dx at the very end

Answer 4

I am SO sorry

Answer 5

lol it's alright I got what you mean, writing it on paper now :)

Answer 6

I am so jealous of you guys who understand calculus :(

Answer 7

\[-13\ln|(x+2)|/3+10\ln|x-1|/3+\ln|x|+c\]

Answer 8

but you can understand calculus if you want to ^_^ all you have to do is learn it and practice to add up the skills

Answer 9

The whole thing inf front of the slash is divided

Answer 10

that was quick mstud, you sure of your answer? :)

Answer 11

and andy , you can do well in mathematics just as you do well with computers ^_^, you're smart

Answer 12

Yes, checked it digitally ^.^

Answer 13

do you know the steps? ^_^

Answer 14

oh! got it! partial fractions! ^_^

Answer 15

Sorry I copied the integral from this webpage, before I solved it, so my answer was wrong, because x^3 was then x*3. The correct answer is: \ln(x^2+4)+2\ln(abs(x-1))+3arcTan(x/2)/2+\ln(abs(x))+c

Answer 16

i guess i am just lazy to learn it... but then sooner or later i will have to learn it in university

Answer 17

If you want to see the solution, just visit WolframAlpha.com and plug in integrate (the expression), so I don't have to write it here with this terrible equation editor...

Answer 18

And maybe my solution here would get full of errors anyway ;_)

Answer 19

oh no, my answer vanished :(

Answer 20

and I got in the end:

ln|x| + 2 ln|x -1| + 3/2 S (3/2x+1)/(x^2+4)dx

you'll have to integrate the last part once more then add it up with the others .

Answer 21
