I am trying to evaluate this integral,(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\[

\int_{ - r}^r {\left( {s\sqrt {1 + \frac{{x^2 }}{{r^2 - x^2 }}} } \right)} {\rm }dx\] [/tex]

Is it a valid integral?

If I evaluate it by plugging in r and -r, it becomes undefined.

How else can I evaluate this integral? I'm in calculus 1 and I am guessing

this may be a topic covered in later calculus classes?

EDIT: I had the integral wrong. It should be,

[tex]\[

\int_{ - r}^r {\left( {s\sqrt {1 + \frac{{r^2 }}{{r^2 - x^2 }}} } \right)} {\rm }dx\] [/tex]

Thanks
