Please help. Sometimes when I want to do some shading of a graph with integration, my CP330 gives me an error.
For example: f(X)=1/sq. rt. (1+x^3). The CP330 didn't like -1 as a lower bound. -1 is in the domain. I just tried it and it worked fine.

Do I need to change a setting?

TIA!

Maybe you should try putting in complex mode... I now realize what you are trying to do. You should have the setting to f(y) instead of f(x). just click on the type menu and select what you want. You can make it greater than or less than. You must have figure that out already.
