Just to be sure everything seems to be on the up and up, show that the
series converges for all t >0 and 0 <x < 1.
Since u (х, 0) — 100.х (1 — г),
400
1- (-1)"
100x (1 – x)
sin nAx
n3
n=1
Let SN (x) be the Nth partial sum of this series.
Plot 100x (1 – x) and the partial sums SN (x) for N = 1, 3, and 5 one-
by-one on the same graph to get a feeling for how well the partial sums of
the series approximate the initial temperature profile.
