Mathcad Prime integrate a piece-wise function?

[dsochor]

Is it possible for Mathcad Prime to integrate a piece wise function? In the attached worksheet I am attempting to integrate a piece-wise function 4 times. If possible I'd like to be able to create a graph of these functions and then pull values from the graph.

Sorry. It's a Mathcad 3.1 file, and Mathcad 3.0 (which is what I have) can't read it. You also can't save it back to version 3.0. Amazing, but true.

Please find in attachment PDF and XPS version of this worksheet.

The graphing error may stem from the fact that you define x from -1ft to ... , but the definition of w(x) is for values of x from 0ft to l.

the function itself is very discontinuous & this may lead to failure to integrate or numerical errors due to rounding and/or aliasing.

In the attachment, a simplified function will integrate, but returns 0.
