I work in Maplesoft’s Applications group. This group is a hub between Sales/Marketing and R&D. I primarily work with customers to help them use our software for their projects.

Born and raised in Windsor, Ontario, I spent a substantial chunk of my life there. I attended the University of Windsor to study Engineering and Math, and moved to Waterloo to start working with Maplesoft.

My first introduction to Maple was in a differential equations class. Our professor swore by it every day, and felt obliged to show us examples on how to use it at the end of every class. Admittedly, I usually skipped out of class right around that point. It wasn’t until I sat down and used the software to do my homework that I truly realized how useful Maple was…I only wish I had heeded my professor’s advice in the first month of the semester instead of the last.

[ Ctrl ]+[ Shift ]+[ " ] will get you above your character.  From there you can enter your dot/line/tild.  Use the right arrow to return back to the base line.

Authors are allowed to submit their work to the app center in any file format that they choose.  In some cases if there are problems with the file running they may have been re-saved on our end to a .mw file (this has only happened in a handful of cases).  Either way, the vast majority of users do submit them in .mw form.

In Maple 12, I would say the easiest way is to use dot notation (ctrl+shift+"), so I can get the equation to look like this

Now if you are interested in seeing a bunch of different ways for entering DE's, might I suggest looking at this Tips & Techniques.

I have moved the post to the appropriate section.

Go to Tools > Tutors > Calculus - Single VariableIntegration Methods.  You can work it out for yourself, or have Maple spit out the steps.

If I am understanding your question correctly, you can use the option "legend=s" to create a legend for your plot (where s is a list of labels for your legend).

 

To show the plot, you need to call the variable you placed the plot in, which is P1.  With what you have, just type P1 and it will display the plot.  If you want to show the plot right away, simply type in plot(x^2, x=-1..1) (which is what Alec suggested above).

For your first question, you have to use the period for matrix multiplication, so you would need to write 4(A.B).C.  That should do it.  To see more about matrix operations, type ?LinearAlgebra and ?Student[LinearAlgebra]

For plotting your set of equations, right click on one of your equations and select plot.  After that you can highlight the other two equations and drag and drop them onto the plotting area.  You can also do this using the "plot" command, as well as the LinearSystemPlot found in the Student[LinearAlgebra] package (look them up in help).

Finally, to solve the matrix, I suggest using the matrix tutor.  You can access it from Tools>Tutors>Linear Algebra>Gauss-Jordan Elimination.  This will let you go through and solve the matrix line by line.

Hope this helps

Your best bet is to look at the list of shortcut keys, or quick reference help.  These will have all of the info you need based on your platform (I'm not on a Mac so I can't pull up the exact keys for you...sorry).  To access the quick reference go to Help>Quick Reference.  To access the shortcut commands go to Help > Manuals, Dictionaries and more > Shortcut Keys.

Hope this helps.

This is just a reminder that if you do come across any anomalies/inconsistencies/bugs with the software, be sure to file an SCR.  The only way we can fix the problem is if we know about it.

Thanks again!

You can use [ ctrl ]+[ shift ]+[ ' ] to go over your variable.  To see a list of 2D operators, go to Help>Quick Reference (or press ctrl+F2).  There is also a Tips & Techniques available on ODE notations available from the app center.

Hope this helps
