Hello page...im taking integral calculus and we are past integration of improper integrals. I know how to use the fundamental theorm but i dont get the first part...[itex] \frac{d}{dx}\int^x_af(t)dt=f(x)[/itex](adsbygoogle = window.adsbygoogle || []).push({});

the book used it in an example....find the dirivative of [tex]g(x)=\int_0^1\sqrt{1+t^2}dt[/tex]....the book goes on to tell you the answer but it show NO STEPS...it is James Stewart Calculus 2nd edition i believe if anyone has the same book..page 383..but anyway can some one go through the steps...plz
