Who can send me a program that can plot a ballistic trajectory under the following conditions...

a) with and without aerodynamic resistance

b) with and without a starting height?

I am still not very good in using maple and the course we had at our school was quite unsatisfying and unprofessionally organized.

Thanx

Is it possible to view the source of a Maple document and correct errors that creep in as the document is edited?

 

Thanks,

In the attached worksheet, I have 4 questions:View 1292_simplifying units 1.0.0.mw on MapleNet or Download 1292_simplifying units 1.0.0.mw
View file details

1. Why don't I see Units when I right-click (rc)?

2. When I see Units in the 2nd instance when I rc, why don't I see Simplify?

Does anybody know whether there's a library with which I can efficiently compute Minkowski-Sums of Polytopes or Polyhedra?

I want to load C++ code into Maple12. Is that possible?

In which format do I need the files (.obj, .exe or just .cpp)?

Thanks!

Hi, I have the next problem:

I have the equation z:=x+y*i, and i have to animate the equation z^3-z+A. I have to animate by the parameter A from -2 to 2. How can i put animate and complexplot together?

thanks a lot =)

So I am doing some algebra calculations with what I thought were Lie Algebras.   It looks like

I was just reminded of an aspect of Maple GUI Components, new to Maple 13, that has sometimes come in very useful to me. It is the ability to refresh a component programatically.

I should explain. The old (and current default) behaviour is for the GUI not to refresh any other components until the current component is finished (ie. returns control).

The relevant situation in which this matters is when a given component has action code whose

 

I have a button and a math container where the button code is given below.

The code simple generate 4 random numbers when you press the button and save the random numbers in a list which

is displayed in the math container.

 

with(DocumentTools):
with(Statistics):

to 4 do

r:=evalf(Sample(RandomVariable(Normal(0,1)),1)[1],1);

if not assigned(LL) then LL:=[r] else LL:=[op(LL),r] end if;

end do;

Do(%MathContainer3=LL);
 

 

How do I number the pages in a Maple worksheet?

I try to fit curve through set of points that I read  from a graph. Then use equation of this curve to define a function function. Only bspline approximation gave acceptable result. But how can I use it in defining a function?

 

XvalsCf := [0, 5, 10, 25, 50, 100, 140, 200, 250, 300, 400]

valsCf := [0.5e-2, 0.4e-2, 0.3e-2, 0.26e-2, 0.23e-2, 0.21e-2, 0.2e-2, 0.19e-2, 0.18e-2, 0.175e-2, 0.15e-2]

 

Another issue is in "surface fitting". Graph shows propeller efficiency curves. I'd like to get equation of surface spread on those curves.  Axis x is an angle, axis y V/nD and z is efficiency.

Again using spline/bspline approximation is nesssary to get accurate results.

I will use this efficiecny surface function equation in drive optimization .

 

Is creation of such surface/function  possible in maple.

 

Thank you in addvance for your help.

I recently optimized a fairly large function with 100+ parameters using the Minimize command. In order to keep track of everything, I gave them logical names (ie. qk0, qk1...). Instead of preserving the order in the output, maple reported the solution as a set and not a list. Can I change this. I know that with minimize (lower-case) I can set location=true. Any ideas for Minimize? Also, what about exporting the results to Excel/Numbers for analysis? All help is greatly appreciated. Steve

I have a function of two variables, f(x,y).
The function does involve in infinite series of functions fn(x,y)

   f(x,y) = sum( fn(x,y) ,  n=-100..100)

but that shouldn't be an issue.

I need to solve numerically the roots of f, obtaining a stored function y(x) over a range x=0..1/2.

Finally, I take y(x) and evaluate another function, g[ x, y(x) ]  over the range of x.
g(x) would be plotted.

here i have an ode system:

diff(x(t),t)=f(x,y,z,w); diff(y(t),t)=g(x,y,z,w);diff(z(t),t)=h(x,y,z,w); diff(w(t),t)=k(x,y,z,w) where f, g, h, k are given nonlinear functions.

Then how can i get the phaseplan of (x(t),y(t))? when i use the procedure of DEplot, it returns an error stating that the DESYS requires two or fewer variables? how can i deal with that?

Any help will be greatly appreciated!

 

I just noticed that in Maple 12 (and 13) the Layout palette's subscripted atomic identifier entry had its hover-over tooltip changed. By hover-over I mean the text based tooltip that appears after a slight delay when the mouse point is allowed to hover over the entry.

In Maple 11 it showed as subliteral which, while perhaps to entirely clear to everyone, was at least accurate. It meant: the unique subscripted name.

For example, x-subscript-y, as a subliteral...
