Homework Statement
Is the set of all complex solutions to the differential equation [tex] \frac{d^2 y}{d x^2} + 2\frac{d y}{d x} - 3 y = 0[/tex]
If so, find a basis, the dimension, and give the zero vector
Homework Equations
The Attempt at a Solution
I solved the equation and got the answer:
[tex]y(x) = C_1 e^{-3x} + C_2e^x[/tex]
I know how to test if a set is a vector space but I'm not really seeing the "set" here. Is it because [tex]C_1[/tex] and [tex]C_2[/tex] can be complex numbers? In which case, wouldn't any complex number work so would I get the set of all complex numbers?
any help is appreciated
