This is our exact differential equation for [R.sub.1] and it determines [R.sub.1] in terms of [R.sub.0]. Solution of Einstein's geometrical gravitational field equations exterior to astrophysically real or hypothetical time varying distributions of mass within regions of spherical geometry Ther...
Exact Differential EquationsIn this section we study another class of first order differential equationswhich, at least in principle, can be solved an..
What is the general form of exact equations? First-order differential equations can be expressed in the general form M(x,y)+N(x,y)y'=0. The equation is exact if M=dF/dx and N=dF/dy for some potential function F(x,y). Register to view this lesson ...
The traditional approach to teaching differential equations is to present a collection of techniques for finding closed-form solutions to ordinary differential equations (ODEs). These techniques seem completely unrelated [1] and have arcane names such as integrating factors, exact equations, variation of...
