31. Tap p o i n t B and then press E to select it.

32.Use the cursor keys to move point B along the graph.

Note that with each move, the results of the calculations

shown at the top left of the screen change. To deselect

point B, tap point B and then press

Calculations in

Plot view

By default, calculations in Plot view are docked to the upper

left of the screen. You can drag a calculation from its dock and

position it anywhere you like; however, after being undocked,

the calculation scrolls with the display. Tap and hold a

calculation to edit its label. An edit line opens so that you can

enter your own label. You can also tap and select a

Trace the

derivative

Point D is the point whose ordinate value matches the

derivative of the curve at point B. It is easier to see how the

derivative changes by looking at a plot of it rather than

comparing subsequent calculations. We can do that by

tracing point D as it moves in response to movements of point

First we’ll hide the calculations so that we can better see the

trace curve.

33. Press

M to return to Numeric view.

34.Select each calculation in turn and tap . All

calculations should now be deselected.

35. Press

P to return to Plot view.
