You'll also need to work the other way, finding the equation for an ellipse from a list of its properties. Write an equation for the ellipse having one focus at (0, 3), a vertex at (0, 4), and its center at (0, 0).; Since the focus and vertex are above and below each other, rather than side by side, I know that this ellipse must be taller than it is wide.

A solution to a second order differential equation is any function that satisfies the differential equation. That is if we find the derivative, , and and substitute them into the DE, then the LHS and the RHS of the equation are equal for all time. Just as with first order differential equations, we can plug solutions back into the differential.
In this section we go through the complete separation of variables process, including solving the two ordinary differential equations the process generates. We will do this by solving the heat equation with three different sets of boundary conditions. Included is an example solving the heat equation on a bar of length L but instead on a thin circular ring.
