Example 17.1.3 y ˙ = t 2 + 1 is a first order differential equation; F ( t, y, y ˙) = y ˙ − t 2 − 1. All solutions to this equation are of the form t 3 / 3 + t + C. . Definition 17.1.4 A first order initial value problem is a system of equations of the form F ( t, y, y ˙) = 0, y ( t 0) = y 0. Here t 0 is a fixed time and y 0 is a number.

new differential equations are The term -kv(t) represents air resistance and k is a constant. The minus sign means that air resistance acts in the direction opposite to the motion of the ball.It is more difficult to solve this problem exactly. So we will not give the solution here. This is an example of a linear ode. Electrical Circuits
