WebCalculus, Differential Equation. A direction field (or slope field / vector field) is a picture of the general solution to a first order differential equation with the form. Edit the gradient function in the input box at the top. The function you input will be shown in blue underneath as. The Density slider controls the number of vector lines. WebThen the slope field will be independent of y. It will look like a lot of "columns" of lines all with the same slope. So on the x-axis the lines will be horizontal, for x=1/2 they'll be diagonal lines, etc. We can solve dy/dx = 2x directly (by integration), giving y = x² + C.
