A [b]vector field[/b] is given by [math]v(x,y) = (v_x, v_y)[/math].[br]The applet shows the vector field for [math]v(x,y) = (x, -y)[/math].[br][br][b]Task[br][/b]Cange the sliders for [br]- the coefficients a and b[br]- step s[br]- the length of the vectors.[br]The red point mark the lower and upper bounds of the vector field.[br][br]Choose other vector field, for example v(x,y) = (a·x² + y, -b·y)[br][br][i]Hint: The arrows are shortened by the factor l.[/i]
