Suppose R = 1, k = 1 and f (r) = r. Assume that U(1,t) = 0
Chapter 17, Problem 17.42(choose chapter or problem)
Suppose R = 1, k = 1 and f (r) = r. Assume that U(1,t) = 0 for t > 0. Use a numerical integration to approximate the coefficients a1, , a5 and use these numbers in the fifth partial sum of the series solution to approximate U(r,t). Graph this partial sum for different values of t.
