 The questioner was satisfied and accepted the answer, or
 The answer was disputed, but the judge evaluated it as 100% correct.

comment: upon reading the answer again I note that I made a miscalculation. In the third equation one should get f(\pi) * (1)  f(0) * (1) instead of f(\pi) *(1)  f(0)*(1)  as cos(\pi)=1 not 1. This should then enter into the second to last equation where you get 4 = f(0) + 9, the solution then becomes f(0)= 49 = 5.

Unfortunately it is not possible to edit answers once they are submitted, which is why I must put the correction in a comment instead.

Yes that is all good, thanks so much for your help!
The answer is accepted.
