Question: A laterally insulated homogeneous bar with ends at x = 0 and x = 1 has initial temperature 0. Its left and is kept at

A laterally insulated homogeneous bar with ends at x = 0 and x = 1 has initial temperature 0. Its left and is kept at 0, whereas the temperature at the right end varies sinusoidally according to u(t, 1) = g(t) = sin 25/3πt. Find the temperature u(x, t) in the bar by the explicit method with h = 0.2 and r = 0.5(one period, that is, o < t < 0.24).
