# Differential equations examples and solutions pdf

The following examples show how to solve differential equations in differential equations examples and solutions pdf few simple cases when an exact solution exists. One must also assume something about the domains of the functions involved before the equation is fully defined.

An equation is analogous to a scale into which weights are placed. If a quantity of grain is removed from one pan of the balance, an equal amount of grain must be removed from the other pan to keep the scale in balance. Likewise, to keep an equation in balance, the same operations of addition, subtraction, multiplication and division must be performed on both sides of an equation for it to remain true. Differential equations are used to model processes that involve the rates of change of the variable, and are used in areas such as physics, chemistry, biology, and economics.
