To solve a system with higher-order derivatives, you will first write a cascading system of simple first-order equations then use them in your differential file.
Several years ago, the math department purchased a set of ten laptop computers.
So we try to solve them by turning the Differential Equation into a simpler equation without the differential bits, so we can do calculations, make graphs, predict the future, and so on.
Why is it that even though modeling can predict negative consequences, as with over-fishing or climate change, it is so hard to get society to take preventive action? The differential equations involving the derivative of one dependent variable with reference to more than one independent variable is called a partial differential.
