Dr. Scot Gould is a professor of physics in the W.M. Keck Science Department of Claremont McKenna, Pitzer, Scripps colleges - members of The Claremont Colleges in California. He was involved in the early development of the atomic force microscope. His research has included numerous applications of scanning problem microscopes, particularly those which involved natural and synthetic fibers such as spider silk. He has more than 60 papers and his publications have been sited more than four thousand times. He has more recently been involved in developing and sustaining non-traditional interdisciplinary undergraduate science educational programs that involve biology, chemistry, physics, mathematical and computer science. He teaches the use of Maple to assist students to model and visual biochemical systems from a physical approach.

Based on my experience with updating numerous copies of Maple, to update within a shorter period of time, I recommend going directly to the Maplesoft website and downloading the update:


Yes, odd. Correct statement appears to be evalb(true) as in: 

if evalb(true) then .... end if;

I too use the right-click button as an instructional tool. In working with this option, I've never seen a menu not show up. However, I've had two situations occur: 1) the first time the menus are loaded, there can be a delay. On some computers, it can be noticable. 2) sometimes one can click on a phrase, either the input or output, and there is nothing for which it can do to it. 

From a pedagogical perspective, I teach the students to write some simple code. For me, nearly all of the math problems can be performed upon learning about 10 commands. But I use the right click for maybe that calculate that requires at most a couple clicks. For a different pedagogical perspective, Robert Lopez should weigh in here. 

I don't quite understand why you want to adjust the size. Regardless, I don't believe such an option exists.

However, I do feel having an option within a right-click menu option would be very useful to those of us who both display plots of a worksheet and print those worksheets. In the former situation, a larger plot is useful, in the later situation, a smaller plot is useful. This might mean establishing a set of sizes: small(100 x 100), medium (200 x 200), large (400 x 400), and default (what was established under plots:-setoptions). 

For inserting equations, plots, etc. from Maple into a Google Doc, I use a screen shot application. In Windows, this is the "Snipping Tool". For me, it works well enough for most situations. 

As an physics instructor who has seen this problems for decades, may I suggest the following: given the symmetry and anti-symmetry of the wavefunction, select initial conditions at x=0 where the system flips from symmetric to antisymmetric, i.e., psi(0)=1, D(psi)(0)=0, etc. This will lead you to more accurate values for the energy of these levels, that is: try different values for E, the value of the energy until your odeplot produces that which are seeking. Using this method to shoot around (often called the “shooting method”), you will obtain a more accurate value for E in whatever units you are using.  I suggest Marko Horbatsch’s book: Quantum Mechanics using Maple.
