For people looking to solve/verify an integral:

  1. Apr 24, 2005 #1
    I've seen a lot of people on these forums asking about integrals or to verify that they have taken a correct integral so I decided to post this. It's a website that will take the integral for you. Use it only to check your answers, as it will not provide you with each individual step. Soo yeah. Use it wisely, especially if you're just learning integrals :wink:


    Here's the link


    Hope this helps some of you! :biggrin:

    Nice site. It will be useful when I forget some integral rules

    Here is another, http://integrals.wolfram.com/. Seems to be based on the same engine.

    It's useless.It cannot solve

    [tex] \int \sqrt{\sin x} \ dx [/tex]

    Why...?Deviously,it can solve

    [tex] \int \left(\sin x\right)^{n} \ dx [/tex]

    in terms of Gauss's [itex] _{2}F_{1} [/itex],but it wouldn't apply it for [itex] n=\frac{1}{2} [/itex]...

    Well, I helped it along a bit with setting [tex]u=\cos(x)[/tex] so that we are to integrate [tex]-\frac{1}{(1-u^{2})^{\frac{1}{4}}}[/tex]
    Then it worked nicely..

    So the software has "bugs"...Interesting,if G & R has a lotta errors,why wouldn't a sofware have its own...?
