solve the equation given and m off for tonight

OpenStudy (anonymous):

\[\int\limits_{0}^{\infty} \frac{ dx }{ x ^{1/3}(1-x)^{1/2} }\]

OpenStudy (anonymous):

hmmm it's an improper integral, can rewrite it as \[\lim_{n \rightarrow \infty}\int\limits_{0}^{n}\frac{ dx }{ x ^{1/3}(1-x)^{1/2} }\]

OpenStudy (anonymous):

maybe you can now use integration by parts

pooja195 (pooja195):

well tp begin with what do you already know

OpenStudy (anonymous):

It's not an equation, dude.

OpenStudy (anonymous):

so what is it? O.o

OpenStudy (anonymous):

It's just an expression. You could call it an integral. Equations require an equal sign.

OpenStudy (anonymous):

oops then can you solve it?

OpenStudy (anonymous):

There is this thing called the beta function, ever hear of it?

OpenStudy (anonymous):

yep

OpenStudy (anonymous):

gamma function and beta function both

OpenStudy (anonymous):

well

OpenStudy (anonymous):

I don't think it has an elementary anti-derivative.

OpenStudy (anonymous):

what can you tell about its convergence

OpenStudy (anonymous):

Remember the \(p\) series.... \[ \int \frac{1}{x^p}dx \]Converges for \(p>1\). Otherwise it diverges.

OpenStudy (anonymous):

olright then gotcha

OpenStudy (anonymous):

Try comparing it to a \(p\) series.
