Given that y(t) = c_1e^10t + c_2e^-10t is a solution of the equation y\" - 100y = 0, where c_1 and c_2 are arbitrary constants, find a function y(t) that solves the initial value problem: y\" - 100y = 0, y(0) = 10, y\'(0) = 100.Solution
Given:
y(t) = c1 e10t + c2 e-10t (1)
(1) is a solution of the equation:
y\'\' - 100 y = 0 (2).
Initial conditions:
y(0) = 10 (3)
y\'(0) = 100 (4)
Putting t = 0 in (1) & using (3), we get:
c1 + c2 = 10 (5).
Differentiating (1), we get:
y\'(t) = 10 c1 e10t - 10 c2 e-10t (6)
Putting t = 0 in (6) & using (4), we get:
10c1 - 10 c2 = 100
So,
c1 - c2 = 10 (7)
(5)+(7) gives:
2c1 = 20
So,
c1 = 10
Sustituting in (7), we get:
c2 = 0.
So, the required solution of the initial value problem is:
y(t) = 10 e10t
