The general solution is derived below. First-Order Linear ODE. Solve a differential equation analytically by using the dsolve function, with or without initial conditions. It is helpful, as a matter of notation first, to consider differentiation as an abstract operation, accepting a function and returning another (in the style of a higher-order function in computer science). A first-order differential equation is defined by an equation: dy/dx =f (x,y) of two variables x and y with its function f(x,y) defined on a region in the xy-plane.It has only the first derivative dy/dx so that the equation is of the first order and no higher-order derivatives exist. Multiply the DE by this integrating factor. There, the nonexact equation was multiplied by an integrating factor, which then made it easy to solve (because the equation became exact).
