A periodic function can be expressed in a Fourier series of the form, Oo fx)= (a, cos nx + b, sin nx). n=0 The functions f(x) = cos x and f(x) = sin x are expanded in their respective Fourier series. f the coefficients for the first series are a, and ba, and the coefficients for the second series al and b = (b) b= and ai = (C) a-and a- (d)b-and b - are a and b, respectively, then which of the following is correct? 2 NaLonistal structure?

Always remember the basic defination of Fourier series is that it is expansion of a function in terms of sine and cos. So basic trigonometric identity can also be the Fourier series. See attached. Ask if any further doubt.
