It would be nice to have the facility Acer suggests. gamma (lower case) is a case in point. It's the symbol representing the ratio of specific heats at constant pressure and constant volume, much used in thermodynamics, and thus the exponent in the adiabatic expansion law, p*v^gamma = constant AFAIK Euler's constant doesn't appear in thermodynamics, so we can get by with the unprotect mechanism, but I would still like to see Acer's suggestion implemented.

That's a great effort DJKeenan and I hope that Maplesoft uses it to good effect. Scattered through Mapleprimes there are numerous suggestions for improving Maple's help pages, perhaps it's not too much to hope that someone at Maplesoft tries to pick them up. But what is really needed is a complete re-write of all the help pages by specialist technical authors to give them a consistency and clarity that's missing right now. IMHO Maple has a long way to go to catch up with MMA in this respect. J. Tarr

My previous post should have read "Maple's r,theta,phi convention is a left-handed system". (The angle phi is defined as the colatitude in ?plot3d[coords] and ?coords.) J. Tarr

Strictly speaking, ISO 31-11 requires rho,phi,theta. However, the main point about ISO 31-11 is that it defines mathematical signs and symbols for use in physical sciences and technology. Maple's r,phi,theta convention is a left-handed system, but presumably accorded with math textbooks in common use at the time. At ?coords gives these References Moon, P., and Spencer, D. E. Field Theory Handbook 2d ed. Berlin: Springer-Verlag, 1971. Spiegel, Murray R. Mathematical Handbook Of Formulas And Tables. New York: McGraw-Hill, 1968. JacquesC might be able to shed some light on this piece of Maple's history. J. Tarr

On Windows XP, I can drag and drop with no problems in Maple 10.06 and Maple 11.01, whether typesetting is set to standard or extended. It looks as though this problem is Mac specific. J. Tarr

Is this what you are looking for? restart; convert(175,base,10); convert(%,base,10,1000); Hope this helps. J. Tarr

Trouble with pursuing the changing color of the Maple leaf is that you end up with a black skeletal leaf. Not very attractive. So I suggest that the thousand be marked instead by a drop of golden Maple syrup. J. Tarr

Is this homework? J. Tarr

Have you tried the example at help for ErrorPlot? That produces vertical yerrors for me. Hope this helps, J. Tarr

A neat trick by Robert Israel produces rational multiples of Pi on the x axis, e.g restart; plot(cos(x),x=0..2*Pi,xtickmarks=[seq(i/2*Pi=i/2*Pi,i=1..4)]); J. Tarr

As far as I can tell there is nothing in the help files for Maple 11.01 about the Maple Reader beta version. Nor have I been able to find anything about it on this site or the Maplesoft website. That's sloppy work by Maplesoft: we expect better of them. J. Tarr

There are many ways of plotting the residuals and its really a matter of personal preference. Take a look over at the Application Center at the Statistics sections and you're sure to find something that appeals to you. Hope this helps, J. Tarr

Scott, You could use identify to find the closed form from the numerical approximation produced by evalf. That yields 1/(2*Pi). Hope this helps J. Tarr
