## Drawing in maple...

Maple

I am preparing a document where in I want to show half circle inide the drawing. I can plot a half circle, but can not bring it inside the drawing canvass. Is there a way to show smooth curves inside the drawing. Pencil tool helps to show my curve, but not a smooth one! In any picture tool, bring forward, sent backward options will be there. Are there such tools in maple?

Cheers.

## Copy paste at times not taking place. Wh...

Maple

I am writing a maths books using maple now. It is fantastic to use maple for writing books in maths.

 in the polynomial  This line is not copying in full line!! Step 1: Find the sum of all the coefficients in the polynomial  This line is copying in full!!                                                  r is a factor  ; 1 is a root of the polynomial. In the next row, I copy pasted the lines above in the polynomial  This line is not copying in full line!! Step 1: Find the sum of all the coefficients in the polynomial  This line is copying in full!!                                                  r is a factor  ; 1 is a root of the polynomial. In the next row, I copy pasted the lines above

Can any one find the reason?

I enclose a part of my document where in I made a particular line with text and maths formats combined.Then I made changes in the line. Now copy paste does work only for the later half (both text and maths formats). The corrected first part is not being copied.

How do I do the corrections properly so that copy paste is not a problem at laer stages.

## Table and sketches inside table not show...

Maple

I like Maple the most for calculation of difficult parts. But when it comes to display, I am ignorant and do not know how to command the maple for showing me what is visible in the document.

I attach herewith my document which shows in print view only top half of the sketch. What should I do to show all three figures in the portrait page.
(Here below, after uploading it is shown alright, but in the print preview it is not showing!!).

I want to convert the doc to pdf. Therefore, in the doc preview itself it should be complete.

Thanks for help.

## Table properties...

Maple

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.

## Symbolic x and y in an equation - How d...

Maple

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.

 Cost in \$: Present Value: Interest in % per year: Period in years: Additional Months

 Principal \$ Interest % per year Year Present value at the year end

UpdateExpr procedure does not update equation, instead turns out a value on LHS

 Cost: Interest % per year (float)
