I know this may sound as a stupid question but I would like to clarify this.
An arbitrary function f can be expressed in the Fourier base of sines and cosines. My question is, Can this method be used to solve any differential equation?
You plug into the unkown function the infinite series and then you get the coefficients from the differential equation itself.
Can anybody tell me why this method may fail?
Thanks!
