These are questions asked by Ramakrishnan

I have made a table and did a programme to do calculations inside.

While converting into a pdf, i found that the table cells being continuous overlaps on pages. I now want to trim the table or split the table to convenient size. Any suggestion.

How do I convert a 7 x 3 table into a 4 x 3 and 3x3 table? Reducing font size does not alter the row and cell size. Is there a way to alter the columnwidth and row height in maple?

Thanks for suggestion.

I have made a document to give the results for a problem in table form and graph form.

The tables work out well. The graph results also come out well when I have that section alone in the document. But it does not give the updated curve here. Please correct me where I made mistake.

Dear members,

Having learnt the use of parse, I tried making a document with module. The document works fine. But I could not not take the codes inside the ComboBoxes inside module UpdateExpr().

Also initialisation does not work since parse command is not allowed by maple here as can be seen by the output in MathContainer_fplusx below.

The document works fine after executing !!!.

Can any one help me avoid all the codes inside combobox except the UpdateExpr() code, please? Thanks.

Ramki.

Dear members,

I have made a simple document with 3 components ComboBox, TextArea and MathContainer.

A selection from ComboBox gets entered into TextArea, but not in MathContainer. I tried all codes with and without quotes, expression, value, "value" etc.

Any simple code I missed, please let me know.

Thanks.

I have made a document with mathContainer, plot component and sliders, which works fine, but needs the startup code to be run manually, everytime to remove the plot error message, popping out in the first instance.

              unrecognized function "inequal" where PLOT DAG expected

I donot know the mistake I have made. 

Thanks for any suggestion. 

Ramki.
