Variation theory of learning was developed by Ference Marton of the University of Gothenburg. One of its basic tenets is that learning is always directed at something – the object of learning (phenomenon, object, skills, or certain aspects of reality) and that learning must result in a qualitative change in the way of seeing this “something” (Ling & Marton, 2011).

– Identifying and solving exact differential equations. We’ll do a few more interval of validity problems here as well. Bernoulli Differential Equations – In this section we’ll see how to solve the Bernoulli Differential Equation. This section will also introduce the idea of using a substitution to help us solve differential equations. If a 2 is zero for some z, then the Frobenius method, a variation on this method, is suited to deal with so called "singular points". The method works analogously for higher order equations as well as for systems. Example usage.

It can also be used to approximate the energies of a solvable system and then obtain the accuracy of the method by comparing the known and approximated energies. Hence, solving the associated partial differential equation of first order is equivalent to finding families of solutions of the variational problem. This is the essential content of the Hamilton–Jacobi theory , which applies to more general variational problems. The general method of variation of parameters allows for solving an inhomogeneous linear equation by means of considering the second-order linear differential operator L to be the net force, thus the total impulse imparted to a solution between time s and s + ds is F (s) ds. 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). Solving Euler’s equation for f+ λgintroduces the new variable, λ, called a Lagrangemultiplier, into the solution.

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. One application of solving linear equations is variation. Often different events are related by what is called the constant of variation. For example, the time it takes to travel a certain distance is related to how fast you are traveling. The faster you travel, the less time it take to get there. This is one type of variation problem, we will look at three types of variation here.
