# Write an equivalent first-order differential equation and initial condition

If it is left out you will get the wrong answer every time. There are different ways of processing mine tailings, but one way is to store them in a pond, especially if water is used in the mining operation. Is the solution globally defined or does it only hold for a small interval?

Multiply the integrating factor through the differential equation and verify the left side is a product rule. Doing this gives the general solution to the differential equation.

If not rewrite tangent back into sines and cosines and then use a simple substitution. In other words, a function is continuous if there are no holes or breaks in it.

Reduction to quadratures[ edit ] The primitive attempt in dealing with differential equations had in view a reduction to quadratures.

A valuable but little-known work on the subject is that of Houtain Cauchy was the first to appreciate the importance of this view. Thus, the volume of our tailings pond is reduced by 50 cubic meters each day, and our tailings pond will become full after days of operation.

Collet was a prominent contributor beginning inalthough his method for integrating a non-linear system was communicated to Bertrand in Several of these are shown in the graph below.

Either will work, but we usually prefer the multiplication route. Now, recall from the Definitions section that the Initial Condition s will allow us to zero in on a particular solution.

When we do this we will always to try to make it very clear what is going on and try to justify why we did what we did. Clebsch attacked the theory along lines parallel to those followed in his theory of Abelian integrals.

Solutions to first order differential equations not just linear as we will see will have a single unknown constant in them and so we will need exactly one initial condition to find the value of that constant and hence find the solution that we were after. The two main theorems are Theorem.

However, we would suggest that you do not memorize the formula itself. Exact Equations — In this section we will discuss identifying and solving exact differential equations. If you multiply the integrating factor through the original differential equation you will get the wrong solution!

Due to the nature of the mathematics on this site it is best views in landscape mode. Linear Equations — In this section we solve linear first order differential equations, i. We will assume that water in our tailings pond is well mixed so that the concentration of chemicals through out the pond is fairly uniform.

Below is a list of the topics discussed in this chapter.

So, to avoid confusion we used different letters to represent the fact that they will, in all probability, have different values. Do not, at this point, worry about what this function is or where it came from.Equivilent first order differential and initial condition? Ask Question. All of the examples in the section specify the condition.

As I write this question, it occurs to me that perhaps I must solve my differential equation. Writing equivalent first order differential equation and initial condition.

2. This equation will not be separable if $$p(t)$$ is not a constant. We shall have to find a new approach to solving such an equation. We could, of course, use a numerical algorithm to solve ; however, we can always find an algebraic solution to a first-order linear differential mi-centre.comer, the fact that we can obtain such a solution analytically will prove very useful when we investigate.

Free linear first order differential equations calculator - solve ordinary linear first order differential equations step-by-step. Linear Equations – In this section we solve linear first order differential equations, i.e. differential equations in the form $$y' + p(t) y = g(t)$$.

We give an in depth overview of the process used to solve this type of differential equation as well as a derivation of the formula needed for the integrating factor used in the solution process. A first-order differential equation is an equation (1) higher-order derivatives).

We point out that the equations are equivalent to Equation (1) and all three forms will be used interchangeably in the text. A solution of Equation (1) is a differentiable function defined on satisfying the initial condition is the solution whose value is.

The initial condition for first order differential equations will be of the form $y\left({{t_0}} \right) = {y_0}$ Recall as well that a differential equation along with a sufficient number of initial conditions is called an Initial Value Problem (IVP).
