In order to provide the best precision possible, this unit employs central difference to perform
differential calculations.
Using Differential Calculation in a Graph Function
• Omitting the tolerance (
tol
) value when using the differential command inside of a graph
function simplifi es the calculation for drawing the graph. In such a case, precision is
sacrifi ced for the sake of faster drawing. The tolerance value is specifi ed, the graph
is drawn with the same precision obtained when you normally perform a differential
calculation.
• You can also omit input of the derivative point by using the following format for the
differential graph: Y2=
d
/
dx
(Y1). In this case, the value of the X variable is used as the
derivative point.
