Hi PF!(adsbygoogle = window.adsbygoogle || []).push({});

Can any of you help me determine a good measure for how "different" two functions are from each other?

I've thought of using something like ##\int_\Omega (f-g)^2 \, dx##. Can anyone recommend a good technique and direct me to the theory so I can understand it well?

Thanks so much!

Josh
