Differential Equation: d^2y/dx^2 + y = 0

[strokebow]

Hi guys,

Is there a general name for equations like this? If so, what is it?

d^2y/dx^2 + y = 0

Any links to webpages about this type of diff eqn would be goof too?

thanksssss

This is an example of a homogeneous, linear, second-order differential equation with constant coefficients.
