Narration. Your Turn. Intelligent Practice. Practice. Linear differential (or difference) equations whose solution is the derivative, with respect to a parameter, of the solution of a differential (or difference) equation. The connection between variational calculus and the theory of partial differential equations was discovered as early as the 19th century. It was shown by P.G.L. Dirichlet that solving boundary value problems for the Laplace equation is equivalent to solving some variational problem. Consider, for example, a given linear operator equation Separable Equations – Identifying and solving separable first order differential equations. We’ll also start looking at finding the interval of validity from the solution to a differential equation.

February 16 Variation Theory Sequences and behaviour to enable mathematical thinking in the classroom - by Craig Barton @mrbartonmaths Category: Solving quadratic equations Now, in the past I have started off a unit of teaching on solving linear equations by explaining to students how the balance method works, and telling them why it is so important. But no-one in their right mind would solve an equation like 3 + x = 8 using the balance method.

will also satisfy Euler’s equation for any λ. This is because Z x 2 x 1 hdx= Z x 2 x 1 (f+λg) dx= Z x 2 x 1 fdx+λ Z x 2 x 1 gdx= Z x 2 x 1 fdx+λC (5.20) and so if fis extremal then hwill also be (the other term is a constant).
