In this example, syntax 1 is used.
Let y be defined by

y= INTEGR(1, 2, "XC", "YC", 0, x_1, x_2)

This is the command for a Riemann integral between x_1 and x_2, using the points of the curve in the Dataslot.
The following Telitab set is placed in the Data slot:

|INTEGR1|
    0
    2 "XC" "YC"
    "1" 1 1
    "2" 2 4
    "3" 3 9
    "4" 4 16
    "5" 5 25
    "6" 6 36
    "7" 7 49
    "8" 8 64
    "9" 9 81
    "10" 10 100|

For x_1 = 2.5 and x_2=5, this relation returns 

y=28.25.

Remark

In case you apply the symbolic addressing of the columns for the description of the point on the curve or surface to compute the differential for, e.g. "Par_x" and "Par_y", please make sure that your Telitab set contains these names. If not, an error message is generated and the calculation is stopped.

Syntax 3 and 4 are similar to syntax 1, but now existing telitabs are used instead of the dataslot.
