Suppose we have an insulated wire, and we apply constant temperature T1 at one end (say where x = 0) and T2 on the other end (at x = L where L is the length of the wire). Then our steady state solution is u(x) = T2 − T1 L x + T1. notebooks classmate

"WitrynaIn other words, we ﬁnd that the Green’s function G(x;x 0) formally satisﬁes L xG(x;x 0) = (x x 0) (7) (the subscript on Lis needed since the linear operator acts on x, not x 0). This equation says that G(x;x 0) is the inﬂuence felt at x due to a point source at x 0. " - In 1d steady state problems at x x0 t t0 is a
