Drag the locator to change the initial condition in the autonomous equation or move the sliders for and . (An autonomous equation is one where the independent variable—here —does not appear explicitly; i.e., and are independent of .) In this case the integrating factor is determined by the constant and the solution at infinity is determined by the constant .
