If you enter the integral with the CAS set to Exact mode, you will be asked to
change to Approx mode, however, the limits of the integral will be shown in a
different format as shown here:
These limits represent 1
×1_mm and 0×1_mm, which is the same as 1_mm and
0_mm, as before. Just be aware of the different formats in the output.
Some notes in the use of units in the limits of integrations:
1 – The units of the lower limit of integration will be the ones used in the final
result, as illustrated in the two examples below:
2 - Upper limit units must be consistent with lower limit units. Otherwise, the
calculator simply returns the unevaluated integral. For example,
3 – The integrand may have units too. For example:
4 – If both the limits of integration and the integrand have units, the resulting
units are combined according to the rules of integration. For example,
