Answer Blanks in the Limits of Integration
This PG code shows how to put answer blanks into the limits of integration.
- Download file: File:LimitsOfIntegration1.txt (change the file extension from txt to pg when you save it)
- File location in NPL:
FortLewis/Authoring/Templates/IntegralCalc/LimitsOfIntegration1.pg
