Witryna1. Introduction A popular application involving an elementary differential equation is Newton’s law of heating, which describes the change in temperature in an object whose sur- roundings are hotter than it is.1 If the temperature at time t is T (t), then Newton’s law of heating is T 0 = α (Ts − T ), T (0) = T0 , (1) where Ts and T0 are ... bupa optical partner networkWitryna15 cze 2024 · First note that it is a solution to the heat equation by superposition. It satisfies u(0, t) = 0 and u(L, t) = 0, because x = 0 or x = L makes all the sines vanish. Finally, plugging in t = 0, we notice that Tn(0) = 1 and so u(x, 0) = ∞ ∑ n = 1bnun(x, 0) = ∞ ∑ n = 1bnsin(nπ L x) = f(x). Example 4.6.1 bupa optical mount gravatt
