Psi(x) = Sumationn CnPhin(x)(adsbygoogle = window.adsbygoogle || []).push({});

in order to find Cn, i have to multiply both side of the above equation by Phi*k(x) and take the integral. The result is Ck if n = k. My question is what is the value of Phi*k(x)?

i know that multiplying both side of the equation by Phi*k(x) would make the function orthonormal when n != k, and normalize when n = k. But i don't know how to find it.
