Second Order Differential Equations[edit | edit source]
A second order differential equation has a given function and terms including the first and second derivatives of that function. There are many techniques that are employed to find solutions to these problems. Different types of problems need different techniques to solve them.
Homogeneous[edit | edit source]
Definition[edit | edit source]
For second order differential equations, a homogeneous equation is one where the right hand side is zero (e.g. ).
Solution[edit | edit source]
