if i say the substitution then it's already solved :P that's the key haha
not hard
shhh hero :S
I didn't say anything relevant :P
i assume you found the substitution already..
I'm not saying anything :P
let u =x^(1/3) ?
haha no mimi ^_^
well, times the denominator and numerator by something? i dont want to go on the wrong track it will get messy
nope either :) just a simple u substitution
u= x^(1/2) ?
still no :p haha
u =x^(1/6) ?
yup! yay :D now solve it >:))
lol, then its long division too lazy
hahaha =)) that's why it's an lgbariddle ;D
Let, Hero do it.. :P
hmmm..
Take u =x^(1/6) and then go ahead with partial fraction . Tiring :P
Yeah. That's the only way to do it (I think).
ahh the beauty of lgbariddles >:))
No it is plum \[\int\limits_{}^{} \large \frac{6u^5} {u^2(u-1)}\] \[\large 6\int\limits_{}^{}\frac{u^3}{u-1} = \large 6\int\limits_{}^{}\frac{u^3-1^3}{u-1} +6\int\limits_{}^{}\frac{1}{u-1}\] Now continue :D
Answer should come within 2 steps :D
shivam you have nnothing now :P
lol. I forgot du everywhere :P
lol du= whatever :P
"shivam you have nnothing now :P "-->????
Is the first integral an arctan of something?
You got to be kidding me @blockcolder just apply u^3-1^3 = (u-1)(u^2+1+u) and cancel the numerator u-1 and denominator u-1
And then complete the square of the denominator and viola! A wild arctan appears!
@blockcolder \[\large 6\int\limits\limits_{}^{}{(u^2+1+u)}du +6\int\limits\limits_{}^{}\frac{1}{u-1}\] \[\large 6u^3/3 + 6u+ 3u^2 + 6\log(u-1)\]
substitute u= x^(1/6) and voila :P
Oh, right. I thought the u^3-1 is in the denominator. Guess I should clean my glasses.
LOL
Yeah, that happens a lot with me. =))
