Interactive plotting of solutions of a differential equation : interactive_plotode interactive_odeplot

Let f (t, y) be an expression depending of two varaiables t and y.
interactive_plotode(f(t,y),[t,y]) draws the tangent field of the differential equation y' = f (t, y) in a new window. In this window, one can click on a point to get the plot of the solution of y' = f (t, y) crossing through this point.
You can further click to display several solutions. To stop press the Esc key.
Input :

interactive_plotode(sin(t*y),[t,y])

Output :

The tangent field is plotted with the solutions of y'=sin(t,y) crossing through the points defined by mouse clicks
