Can you help me with question 3?

1. Boundary Value Problem with Nonhomogeneous ODE.
For each choice of g(x) listed below, find all solutions to the following boundary value problem.
4y" + x°y = g(x) for 0 < x < 2, y'(0) = 0, y'(2) = 0.
(а) д(x) %3D0
(b) д(x) %3D х
2. Eigenvalue Problem with first derivative in linear operator.
Find the eigenvalues and eigenfunctions for the boundary value problem,
y" + 4y' + ly = 0 on 0 < x < 1, y'(0) = 0, y'(7) = 0.
3. Fourier Trigonometric Series.
-n <x < 0
0sx < 7/2 and its Fourier series
n/2 s x <n
0,
Consider the function f(x) defined on (-7, 7), f(x) ={ 1,
0,
f(x) ~
(a, cos(nx) + b, sin(nx)).
(a) Derive expressions for ao, an and bn, for n = 1,2, ....
(b) Write out the terms of the Fourier series through n =
= 5.
(c) Graph the periodic extension of f(x) on the interval (-37, 37) that represents the pointwise convergence
of the Fourier series in part (b). At jump discontinuities, identify the value to which the series converges.
4. Eigenvalue Problem for Cauchy-Euler Equation.
Find the eigenvalues and eigenfunctions for the boundary value problem,
4x²y" + 4xy' + Ay = 0, on 1 < x < 4,
y(1) = 0, y'(4) = 0.
