Unformatted text preview: 42 Chapter 3 Partial Differential Equations in Rectangular Coordinates Note that A is a finite number because f is bounded, so its absolute value is bounded and hence its integral is finite on [0, L]. We have bn sin nπ −λ2 t0 xe n L 2 ≤ Ae−λn t0 = Ae− ≤ A e− c2 π 2 t0 c2 π 2 t0 L2 c2 π 2 t0 2 n L2 n = Arn , where r = e− L2 < 1. Take Mn = Arn . Then a holds and convergent because it is a geometric series with ratio r < 1. Mn is ...
