Let K be a positive integer. Suppose that you have a function f(r) which you know is of the form K (to +(a, cos(nx) +b, sin(n)), but you don't know the values of the coefficients no....ug and b.bg. Describe how you can deduce those values from integrals of the form -2 (r) cos(ma) dr and 1(r) sin(mr) dr. In other words, give formulas for the a, and the b, in terms of the integrals in equation (4). (Hint: use the previous problem.) h
