Compute its Fourier series?

Consider the function f(x)=2x2+3x+1 defined in the interval [−2π,2π] and extend it as a periodic function with period 4π.

Compute its Fourier series:

f(x)∼12a0+∑n=1∞(ancos(ωnx)+bnsin(ωnx))

    This is just "plug & play". Use the formulas (which you should know by heart) to calculate the an & bn, the ao and  ω . 

    Show your preliminary work here if need be and then we'll take it from there.
