Question
We know that y₁(x) = e
differential equation y" -
is a solution to the
uy' + 1vvy - u for
x = (-∞, ∞). Use the method of reduction of order to
find a second solution to y" – 20y' + 100y = 0 for
x = (-∞, ∞).
e10x
(a) After you reduce the second order equation by
making the substitution z = u', you get a first order
equation of the form
2 = f(x, z) =
Note: Make sure you use a lower case z, (and don't use
z(t), it confuses the computer).
(b) A second solution to y" - 20y + 100y = 0 for
x = (-∞, ∞) is
y₂(x) =
