Slope Fields

Enter a first-order differential equation as an expression in x and y. Move the red points around to see solution curves for different initial conditions. You can adjust the x and y sliders to show more of the slope field, the density for the number of tangents, and the length to change the length of each tangent. To change the viewing window, hold the shift button and left-click to drag the graph or use the scroll wheel to zoom in/out. You can also adjust the axes by holding the shift button and left-click on the axis you want to change.
