An Implicit Differential Equation Example:
This section shows how to solve equations of the following form:.
= f(x, U, Ux, Uxx, ...)
This is a general form of an implicit differential equation. To solve for Uxx in Calculus programming we add the following code right after "model PDE" statement in these examples:
find Uxx; In ImplicitDE; ooo to match error end model ImplicitDE error = Uxx - f(x, U, Ux, Uxx, ooo) error = error**2
This 'find' statement will vary its parameters (ie. Uxx) until 'error' equals zero. Thus you will have a value where
Uxx = f(x, U, Ux, Uxx, ooo)
