You should see an icon that looks like a piece of paper torn in half. We will also need to avoid division by zero. Therefore all we need to worry about is division by zero and negatives under the outer root. We are now going to start looking at nonlinear first order differential equations. Notice that weve actually got two solutions here (the ) and we only want a single solution.

We first rewrite the differential equation as the following you will have an implicit solution that you can hopefully solve for the explicit solution, for many of these solutions. In the add this website box internet explorer should already have filled in lamar. We check to see that x(t) satisfies the ode begingather diffxt 5ce5t 5x-3 5ce5t 3-3 5ce5t. Finding intervals of validity from implicit solutions can often be very difficult so we will also not bother with that for this problem. Also most classes have assignment problems for instructors to assign for homework (answerssolutions to the assignment problems are not given or available on the site).

As with the linear first order officially we will pick up a constant of integration on both sides from the integrals on each side of the equal sign. Because i wanted to make this a fairly complete set of notes for anyone wanting to learn differential equations i have included some material that i do not usually have time to cover in class and because this changes from semester to semester it is not noted here. The section will show some very real applications of first order differential equations. You will be presented with a variety of links for pdf files associated with the page you are on. Recall that the interval of validity was the range of the independent variable, in this case, on which the solution is valid. This is actually a fairly simple differential equation to solve. Now customize the name of a clipboard to store your clips. The first type of nonlinear first order differential equations that we will look at is separable differential equations. This will be one of the few times in this chapter that non-constant coefficient differential equation will be looked at. Finally solving for s that will not give division by zero or square roots of negative numbers will be, this differential equation is easy enough to separate, so lets do that and then integrate both sides.
