∫
dx: The following four inputs are required for integration calculations:
a function with the variable
x; a and b, which define the integration
range of the definite integral; and
n, which is the number of partitions
(equivalent to N=2
n
) for integration using Simpson’s rule.

d/dx : Three inputs are required for the differential expression: the
function of variable
x , the point ( a ) at which the differential coefficient
is calculated, and the change in
x ( Δ x ).

Rnd : The argument of this function is made a decimal value and
then rounded in accordance with the current number of display digits
setting (Norm, Fix, or Sci). With Norm 1 or Norm 2, the argument is
rounded off to 10 digits. See

Note: Using functions can slow down a calculation, which may delay
display of the result. To interrupt an ongoing calculation before its
result appears, press A.
