To locate the minimum velocity click Menu/Find x.../given f'(x) in the Functions window	8421376
40
then enter 0 for "Find values for x, given f'(x) = ".	8421376
41
The wavelength for the slowest ripple is about 0.00271 m.	8421376
42
Left click on this value to copy, then click on the "Evaluate" button in the Functions window	8421376
43
and paste the x value in the "x = " field. { use shift/insert keys to paste }	8421376
44
This calculates the value for y when x = 0.00271. It should be about 0.2305.	8421376
45
That is, the minimum velocity for ripples on water is about 0.2305 m/s.	8421376
46
The precision of the value found depends on the resolution of the graph.	8421376
