Sure, this could also appropriately be placed under linear alg. this being said, can anyone give me an intuitive explanation for the real inner product? i realize it as:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]<f(x),g(x)>\doteqdot\int_a^bf(x)g(x)dx[/tex]

where i can think of this as an "infinite" dot product along a to b. geometrically (and intuitively) what does this represent about two functions, say in [tex]R^3[/tex] for ease of visualization.

for what its worth this has shown up in a fourier analysis course
