Trace the

Point D is the point whose ordinate value matches the

derivative

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

 

B.

 

 

 

 

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

 

trace curve.

 

 

 

35. Press Mto return to Numeric view.

 

 

36.Select each calculation in turn and tap

. All

 

 

calculations should now be deselected.

 

 

37.

Press Pto return to Plot view.

 

 

38.Press Eand select point GD.

 

 

39. Tap

and select More > Trace

 

 

40.Press Eand select point GB.

 

 

41.

Using the cursor keys,

 

 

 

move B along the curve.

 

 

 

You will notice that a

 

 

 

shadow curve is traced

 

 

 

out as you move B. This

 

 

 

is the curve of the

 

 

 

derivative of 3sin(x).

 

Plot view in detail

In Plot view you can directly draw objects on the screen using various drawing tools. For example, to draw a

circle, tap and select Circle. Now tap where you want the center of the circle to be and press

E. Next, tap a point that is to be on the circumference and press E. A circle is drawn with a center at the location of your first tap, and with a radius equal to the distance between your first tap and second tap.
