Can anybody please help me solve the following differential equation:
d^2y/dx^2 + 3(dy/dx) +5y = 0, y(0) = 2, dy/dx(0) = 0
Even a a simple guide to solving this would be great.
How did you get the roots? Im a bit rusty with complex numbers, but you've lost me.
I cannot get the same answer as you.
here is what ive done:
m^2 + 3m + 5 = 0
(m+3/2)^2 = -11/4
m = -3/2 + or - sqrt(-11/4)
m = -3/2 + or - (11i/4)
How did you get m= -3/2 + or - 2i?
