Differentiating y 2 = 4ax . Solution of differential equations by method of separation of variables, solutions of homogeneous differential equations of first order and first degree. B. di erential equation (ODE) of the form x_ = f(t;x). Active today. An ordinary differential equation (ODE) is an equation containing an unknown function of one real or complex variable x, its derivatives, and some given functions of x.The unknown function is generally represented by a variable (often denoted y), which, therefore, depends on x.Thus x is often called the independent variable of the equation. If the change happens incrementally rather than continuously then differential equations have their shortcomings. This might introduce extra solutions.
