Slope field

（重定向自Direction Field）
The slope field of dy/dx=x2-x-2, with the blue, red, and turquoise lines being (x3/3)-(x2/2)-2x+4, (x3/3)-(x2/2)-2x, and (x3/3)-(x2/2)-2x-4, respectively.

In mathematics, a slope field (or direction field) is a graphical representation of the solutions of a first-order differential equation. It is useful because it can be created without solving the differential equation analytically. The representation may be used to qualitatively visualize solutions, or to numerically approximate them.
