I am a fan of using dot charts as opposed to bar charts (R and S users are familiar with these - it is like a horizontal bar chart only there is a dot plotted where the end of the bar would be,  for an example see  I figure Maple is flexible enough so that I could program a function to do this but maybe it is already there or someone else has already done this and I just don't know how to find it.


I got the space curve r=cos(t)i+2tj+sint(t)k and t =(3pi/4)

and i should show the space curve and derivative of r and osculating sphere and osculating plane and osculating circle in

one graph. I know about derivative and display method in maple 11 and knows how to compute into graph

but i am now sure about oscualting sphere, plane, and circle.

Please some one show me how to plot and graph osculating sphere, plane and circle in one graph!


Hey guys, I'm having a hard time with this question my professor assigned to my class.


Here it is:

The temperature on a metal plate is given by T(x,y) = 4x^2 - 4xy + y^2.  AN ant walks around the origin along the circle of radius 5 centered at the origin.  What are the highest and lowest temperatures encountered by the ant? Plot the temperature function and the points of highest and lowest temperatures together on one plot.


I would appreaciate any help.

Is there any way to put the Advanced Engineering Mathematics ebook into a menu on Maple?

After installation I thought it would have to put itself into a menu and be accessible that way or at least under the help file heading, I can't find it in any menu.  The only way I can load the thing is to go to the folder it was installed and load the Table of contents file, or drag it into maple, or do the normal open file ... search for it ... then open. 

If anyone can advise me about how to create the tool that I describe below, that would be great. I am a novice to Maple and object-oriented programming, but I can program in C and I suspect that I can write a Maplet, if that is indeed the best way to achieve my goal. This is what I want to do.

How can I tell to Maple that the sum: Sum(v(n)*S(n),n=1..N) where S(n+1) = S(n) + xi(n+1) can be rewritten as: Sum(x(n)*xi(n),n=1..N) where x(n)=Sum(v(k),k=n..N) ? thanks
hi, would appreciate some help in checking limit series in Maple using d'Alembert's test for convergence (if it's possible). the only limits I can get in Maple is either ∞ or 0 (and I need to be more specific). thanx a lot!

I attempt to draw a 3d plot using plot3d.  The function contains a weighted combination of absolute values.  To simplify the problem statement, suppose drawing -abs(x-y) for x=-1..1, y=-1..1.  It was found that near the zero plane, the plot become sawtooth like, which is an unexpected result.  How can I remove this effect?

How does one do the indeterminate vector product with and Dyadic calculus operations with Maple 12?

Does Maple support Ternary diagrams that can be used for exploring parameters like thee phase relative permeabilities


I just upgraded to Maple 12 because of its ability to perform abstract index calculations. However, I'm having trouble getting started with it. My first problem is with the Simplify command: if I define a completely symmetric tensor using the command


and an antisymmetric tensor using the command




correctly returns 0. However, if I define T to be symmetric in only its first two indices,


Hi all,

I just found Advisor by Robert Israel.  I followed the instructions, but it won't work

Here's what I did.

I unzipped the 3 files (maple.hdb, maple.ind and maple.lib) in the zipped folder to an advisor named directory in the Maple folder

I created Maple.ini and put   libname:= `c:/Program Files/Maple 11/Tools/Advisor`, libname:   as the sole line in the file as it says.  I put the Maple.ini in the main Maple 11 folder and also tried it in it's folder.  No luck.

I have the expression

p(x,a) w''(x) + q(x,a) w'(x) + r(x,a) w(x)

How could I obtain p(x,a), etc.?



*Find the cubic ax^3+bx^2+cx+d that has a local minimum at (‐1, ‐2) and a local maximum at (4, 4). Plot it.

How do i approach this problem?
