I want ot add an annotation to a plot using the drawing facility. Then I export the plot. My problem is that I cannot increase the viewport of the plot without also increasing the size of the plot. For example the code:

plot(20-(20*(1/10))*P, P = 0 .. 10, labels = ["Q", "P"], scaling = constrained, tickmarks = [5, 3], size = [600, 400])

 

produces this plot:

I have constrained the plot and used the size option which together have the side effect of giving me more horizontal space. But this is a wretched hack! I want to size the viewport of the plot so I can write on it.

 

I have a workbook that derives the Cobb-Douglas factor demand functions:

The final formulas (10) and (11) are not in the same format as the formulas in my textbook (by Hal Varian). In fact my last formulas betray no obvious symmetry while Varian's forms do.

Here is a picture of them scraped from the text.

 

Is it possible to instruct Maple to obtain these forms?

Maple 17 is very exciting so I am hopeful ....

Maple evaluates:

but when I ask:

Maple will verify sin(u)/cos(u)=tan(u) but beyond that it does not seem to work too well. I suspect this has something to do with verify being a "semi-boolean" function but searching the docs for what that mean returns no results. It may mean "I am unable to decidee". But how should I know? :-(

This is Maple 2016.1 on Windows. There is a post on verifying very simple identities.

Edit As usual some very helpful answers for which many thanks. It is poor that Maple does not document the meaning of FAIL.It seems that for trig identities the expandverfier is the best.

Edit Maple documents FAIL under ? FAIL. I am not sure how I got a blank page when I searched.

 

I have a Maple result presented in the first (top) formula which I would like to format as in the second (bottom) formula:

Can this be done? This is Maple 2016.1

I would like the C-Text style in 14pt Times Roman while the C-2D-Math style is 12pt.

My use case is that I am typing in a single execution block.

I use Format >> Styles and select the style for C-Text and set it to 14pt Times. I click OK to close the dialog. Next I repeat this for the C-2D-Math style but this time set the font size to 12pt and, for testing, the colour to blue. The effect is to give me 14pt Times for both styles, though the C-text is black and the 2-D-Math is blue.

Can the effect I want be achieved, or is this a bug/feature?

This is Maple 2016.1 on Windows 10 64bit

 Thanks for any help
