Unformatted text preview: as . Now suppose we want to approximate by another function, , which is a linear combination of only the first basis functions, i.e. . We want the approximation to be the one which minimizes the integral squared error, i.e. we want to choose such that is minimum. Show that the solution has coefficients so that . Hint: Use the energy theorem applied to the function ....
