# Plotting the Solution

A plot of the solution given by DSolve can give useful information about the nature of the solution, for instance, whether it is oscillatory in nature. It can also serve as a means of solution verification if the shape of the graph is known from theory or from plotting the vector field associated with the differential equation. A few examples that use different Wolfram Language graphics functions follow.

Here is the general solution to a linear first-order equation.
 In:= Out= The solution can be plotted for specific values of the constant C using Plot. The use of Evaluate reduces the time taken by Plot and can also help in cases where the solution has discontinuities.
 In:= Out= Here is the plot for a linear second-order ODE with initial values prescribed at 0.
 In:= Out= In:= Out= This nonlinear equation has two solutions that can be plotted on the same graph.
 In:= Out= In:= Out= The solution to this Abel ODE is given in implicit form.
 In:= Out= A contour plot can be used to study the nature of the solution. Each contour line corresponds to a solution to the ODE for a fixed value of C.
 In:= Out= In:= Out= Here is the plot of the solutions to a system of two linear ODEs. The WorkingPrecision option in Plot is required because the solution is fairly complicated.
 In:= Out= In:= Out= The ParametricPlot function can be used to trace the solution curve {x[t],y[t]} in the plane.
 In:= Out= Here is the plot for the solution to a DAE.
 In:= Out= In:= Out= Here is the general solution to a linear PDE.
 In:= Out= Here is a plot of the solution surface for a particular choice of the arbitrary function C.
 In:= Out=
