What happened to the one on the left? The answer is quite straightforward. We do actually get a constant on both sides, but we can combine them into one constant K which we write on the right hand side.

Clebsch attacked the theory along lines parallel solution differential equation those followed in his theory of Abelian integrals.

Lie's theory[ edit ] FromSophus Solution differential equation 's work put the theory of differential equations on a more satisfactory foundation.

He showed that the integration theories of the solution differential equation mathematicians can, by the introduction of what are now called Lie groupsbe referred to a common source, and that ordinary differential equations that admit the same infinitesimal transformations present comparable difficulties of integration.

He also emphasized the subject of transformations of contact. Lie's group theory of differential solution differential equation has been certified, namely: The theory has applications to both ordinary and partial differential equations. Example 2 Solve the following IVP and find the interval of validity for the solution.

This is actually easier than it might look and you already know how to do it. So, upon using the quadratic formula on this we get. In fact, only one of the signs can be correct. So, to figure out which one is correct we solution differential equation reapply the initial condition to this.

Only one of the signs will give the solution differential equation value so we can use this to figure out which one of the signs is correct. The explicit solution for our differential equation is. To do this we solution differential equation need to solve the following inequality. Finally, a graph of the quantity under the radical is shown below. Here is graph of the solution. Example 3 Solve the following IVP and find the interval of validity of the solution. These two functions are not the only solutions to the differential equation however.

Any of the following are also solutions to the differential equation. This example leads us to a solution differential equation important fact that we will use in practically every problem in this chapter.

This will work for any linear homogeneous differential equation. Since we have two constants it makes sense, hopefully, that we solution differential equation need two equations, or conditions, to find them.

### 1. Solving Differential Equations (DEs)

We do solution differential equation a brief introduction to boundary values in a later chapter if you are interested solution differential equation seeing how they work and some of the issues that arise when working with boundary values.

Another way to find the constants would be to specify the value of the solution and its derivative at a particular point. As with the first order differential equations these will be called initial conditions.

Example 2 Solve the following IVP.
