What we are doing is writing the equation in differential form. A differential equation is an equation for a function with one or more of its derivatives. The solution of is obtained by separating variables and finding an antiderivative as , or, as this requires that x3 + C must always be positive, . Although some differential equations have an exact solution and can be solved using analytic techniques with calculus, many differential equations can only be solved using numerical techniques. Hence the derivatives are partial derivatives with respect to the various variables. TYPE - 1: VARIABLE SEPARABLE FORM.

Read lecture notes, section 2 on pages 2–4; Three part question which involves setting up and solving separable differential equations. A ﬁrst-order differential equation is said to be separable if, after solving it for the derivative, dy dx. In this section, we describe and practice a technique to solve a class of differential equations called separable equations. If both sides of a separable differential equation are divided by some function f( y) (that is, a function of the dependent variable) during the separation process, then a valid solution may be lost. For instance, questions of growth and decay and Newton's Law of Cooling give rise to separable differential equations. Thus, such a DE is of the form \[f(x)dx + g(y)dy = 0\] which can be solved by straightforward integration to … In theory, at least, the methods of algebra can be used to write it in the form∗y0= G(x,y). A separable differential equation is one that may be rewritten with all occurrences of the dependent variable multiplying the derivative and all occurrences of the independent variable on the other side of the equation. If G(x,y) can be factored to give G(x,y) = M(x)N(y),then the equation is called separable. As a final step, you must check whether the constant function y = y 0 [where f (y 0) = 0] is indeed a solution of the given differential equation. \[\begin{equation}N\left( y \right)\frac{{dy}}{{dx}} = M\left( x \right)\label{eq:eq1} \end{equation}\] Note that in order for a differential equation to be separable all the \(y\)'s in the differential equation must be multiplied by the derivative and all the \(x\)'s in the differential equation must be on the other side … Here is a set of practice problems to accompany the Linear Differential Equations section of the First Order Differential Equations chapter of the notes for Paul Dawkins Differential Equations course at Lamar University.
