What Is Differential Equation Of First Order?

What Is Differential Equation Of First Order? A first order differential equation is an equation of the form F(t,y, ̇y)=0. A solution of a first order differential equation is a function f(t) that makes F(t,f(t),f′(t))=0 for every value of t. Here, F is a function of three variables which we label t, y, and ̇y.
