Question

Which of the following defines a differential equation?

Options

• An algebraic identity that relates independent variables without any rate of change

• An equation that contains derivatives of one dependent variable with respect to one or more independent variables

• An equation containing only algebraic terms with no derivatives

• An equation containing only integrals of independent variables

Answer 1

A differential equation is defined as an equation that contains derivatives of one dependent variable with respect to one or more independent variables. It is used to model situations where quantities change in relation to one another.
