The solution to the first order ordinary differential equation . M(x, y) dx + N(x, y) dy = 0. can be written in the implicit form . u(x, y) = c , (where c is a constant). If M(x, y) and N(x, y) can be written as the first partial derivatives of some function u with respect to x and y respectively, then Clairaut’s theorem,

Implicit and Semi-Implicit Schemes Consider once again the trivial linear ODE (6.42) with y(0) ( 1. We can modified the Euler method by evaluating the RHS at the “new” step instead of the “old”, i.e., (6.43) This procedure is sometimes called the backward Euler method since it can be derived using the backward-difference approximation ...

In section 2.2, we saw that separable first-order equations came from considering an implicit equation defined by . Differentiating both sides gave: Which is identical to the form of . Now we worry about the more general equation . If once again the solution comes from , then . Thus: Theorem 2.6.1: Exact Differential Equations and Their Solution

The last equation is an (implicit) solution of (2.2). A device which is useful for remembering this method of solution is to write equation (2.2) as. and then change to the following differential form. 2.3 The solution is then found by formally integrating each term.

: If y = 0 is a solution to a differential equation on an interval I, then y = 0 is called the trivial solution to that differential equation on I. e.g., = 3y. y = 0 trivial solution. y = c e3x general solution (d) Explicit solution: y = f(x) e.g., y = c e3x is an explicit solution of y' = 3y (e) Implicit solution: f(x, y) = 0

In [3] an ODE (for which the analytic solution was known) has been integrated between xS = 3.92 and xT = 5.54 by using a third-degree polynomial CF4. The superposed graphic of the known analytic solution (continuous curve) and CF4 solution (dotted curve) for a single element is given in Fig.1.

The Runge-Kutta methods are an important family of implicit and explicit iterative methods for the approximation of solutions of our ODE. On them, apply Simpson's rule: Exercise 1. Apply the Euler's, improved Euler's and the Runge-Kutta methods on the ODE. to approximate the solution that satisfy from to with . We know the exact solution is .

Hence y2+x-4=0 is an implicit solution if it defines a real function on (-(,4). Solving the equation y2+x-4=0 for y, we get y= . Since both y1 = and y2 = - and their derivatives are functions defined for all x in the interval (-(,4). , we conclude that y2+x-4=0 is an implicit solution on this interval.
