First Order Differentials
|Top Previous Next|
To enter a first order differential, include a y ' or f '(x) in the function definition. For example, type
Each little line shows the slope at the point. If you hover over one of the slope lines, the graph tool will calculate the slope at that point.
If you select the Marked Point tool.
and add a point on top of one of the slope lines.
the graph tool will solve the differential equation at the marked point and show you on screen. You can add multiple points if you wish.
