A simple integration prob
\[\int\limits_{}^{}(5x ^{3}+9x-4)/(x(x-1)(x ^{2}+4))\]
oh forgot a dx at the very end
lol it's alright I got what you mean, writing it on paper now :)
I am so jealous of you guys who understand calculus :(
\[-13\ln|(x+2)|/3+10\ln|x-1|/3+\ln|x|+c\]
but you can understand calculus if you want to ^_^ all you have to do is learn it and practice to add up the skills
The whole thing inf front of the slash is divided
that was quick mstud, you sure of your answer? :)
and andy , you can do well in mathematics just as you do well with computers ^_^, you're smart
Yes, checked it digitally ^.^
do you know the steps? ^_^
oh! got it! partial fractions! ^_^
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
i guess i am just lazy to learn it... but then sooner or later i will have to learn it in university
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...
And maybe my solution here would get full of errors anyway ;_)
oh no, my answer vanished :(
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 .
