Solve the Laplace equation ∇^2(u)=0 (two dimensions so ∂^2/∂a^2
+ ∂^2/∂b^2) where the boundaries of the rectangle are 0 < a <
m, 0 < b < n with the boundary conditions:
Consider the differential equation x′=[2 4
-2 −2],
with x(0)=[1 1]
Solve the differential equation where x=[x(t)y(t)].
x(t)=
y(t)=
please be as clear as possible especially when solving for c1
and c2 that's the part i need help the most
7. (a) Solve the wave equation in three dimensions for t > 0
with the
initial conditions φ(x) = A for |x| < ρ, φ(x) = 0 for |x| >
ρ, and
ψ|x| ≡ 0, where A is a constant. (This is somewhat like the
plucked
string.) (Hint: Differentiate the solution in Exercise 6(b).)
((b) Solve the wave equation in three dimensions for t > 0
with the
initial conditions φ(x) ≡ 0,ψ(x) = A for |x| < ρ, and...
Solve the IVP:
u'' + 10u' + 98u = 2sin(t/2)
u(0) = 0
u'(0) = 0.03
and identify the transient and steady state portions of the
solution.
Plot the graph of the steady state solution.
