Question
Consider applying the method of separation of variables with u(x, t) = X(x) T(t) to the partial
differential equation
8² u
0x²
+2u= =
du
Ot
du
+2=
dt
Select the option that gives the resulting pair of ordinary differential equations (where is a non-zero
separation constant).
Select one:
O X'(x) + 2X'(x) = µX(x), Ï(t) + 2 = µT(t)
OX" (x) + 2 = μ, T(t) + 2T (t) = μ
fky
OX"(x) + 2X(x) = μX(x), T(t) + 2T (t) = µT(t)
O X'(x) + 2X'(x) = µ, Ï(t) + 2 = μ
