Consider a rectangular membrane with fixed boundaries of dimensions 5 (horizontal)
by 3 (vertical). The deflection u(x, y, t) satisfies the equation utt = 6(uxx + Uyy).
(a) Find a formula for the deflection u(x, y, t), if the initial velocity g(x, y) is zero
and the initial displacement f(x, y) is
f(x, y) = u(x, y, 0) = 2 sin(5πx) sin(лy) - 4 sin(2x) sin(3лy)
Do not show the separation of variables. Start with the formula for u(x, y, t).
You need to show all details of integration or superposition (if it applies) for credit.
(b) Find a numerical approximation for u(5/2, 3/2, 2).
(a) Find the general solution to the following differential equation. Express your
answer in terms of Bessel functions of the first and second kinds. Do not write
any series expansions of these Bessel functions. Please explain how you
arrived at your answer.
x²y" + xy' + (2x² - 5)y = 0
(b) Solve the heat flow problem. Please start with the formula for u(x, t); Do not
show separation of variables. Simplify your answer as much as possible.
