Determine whether each of the following functions is a solution of Laplaces equation u xx + u
Question:
Determine whether each of the following functions is a solution of Laplace’s equation uxx + uyy = 0.
(a) u = x2 + y2
(b) u = x2 − y2
(c) u = x3 + 3xy2
(d) u = ln√x2 + y2
(e) u = sin x cosh y + cos x sinh y
(f) u = e−x cos y − e−y cos x
