differential equation: an equation involving the derivatives of a function; The predator–prey equations are a pair of first-order, non-linear, differential equations frequently used to describe the dynamics of biological systems in which two species interact, one a predator and one its prey. 2021-02-01
Differential equations are the language of the models we use to describe the world around us. In this mathematics course, we will explore temperature, spring systems, circuits, population growth, and biological cell motion to illustrate how differential equations can be used to model nearly everything in the world around us. Solve Differential Equation with Condition. In the previous solution, the constant C1 appears because no condition was specified. Solve the equation with the initial condition y(0) == 2.The dsolve function finds a value of C1 that satisfies the condition.

Solving differential equations means finding a relation between y and x alone through integration. We use the method of separating variables in order to solve linear differential equations. We must be able to form a differential equation from the given information. used textbook “Elementary differential equations and boundary value problems” by Boyce & DiPrima (John Wiley & Sons, Inc., Seventh Edition, c 2001). Many of the examples presented in these notes may be found in this book.
