Access detailed explanations (illustrated with images and videos) to 283 questions. Differential equations involve the differential of a quantity: how rapidly that quantity changes with respect to change in another. An ordinary differential equation (ODE)is an equation that contains one or several derivatives of an unknown function, which we usually call y(x) (or sometimes y(t) if the independent variable is time t).The equation may also contain y itself, known functions of x (or t), and constants.For example, (1) y cos x, (2) y 9y 0, (3) x2y y 2exy (x2 2)y2 are ordinary differential equations (ODEs). 4.
