Be f:$$(0,2\pi) \to \mathbb{R}$$ definid to $$ f(x) = ax^2+bx+c $$ on what a,b and c are real constants.
Determine the value (s) of the parameters a,b and c is that there is a extension $$2\pi - periodic $$ de f which is a continuous function.
I needed help finding those values so I could do the Fourier series later. Can you help me?
