Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more. A direction field (or slope field) is a graphical representation of a differential equation that shows how the slope of the solution curve varies over the plane. To graph a direction field on desmos, you can use one of these methods: Use a vector field generator and enter your differential equation as dy/dx = f(x,y). Definition. A direction field (slope field) is a mathematical object used to graphically represent solutions to a first-order differential equation. At each point in a direction field, a line segment appears whose slope is equal to the slope of a solution to the differential equation passing through that point.Welcome to the Desmos Graphing Calculator!
