Hi

I have some calculations/results which I use in many other documents. Is there anyway to link to this document that contains results I need for another sheet in the beginning of the sheet I need the calculations for?

 

Thanks in advance

Regards Brian

If you make a misspelling in spacecurve as in

plots:-spacecurve([ARctan(t),t,t], t=0..10);

then Maple 13.02 (Standard) loses contact with the kernel.

Even if you forget 't ='  as in

plots:-spacecurve([ARctan(t),t,t],0..10);

Maple will lose contact.

It seems that also Maple 12 has a problem.

Maple 13 Classic doesn't have the problem.

Will these and other 3d-plot problems be corrected in Maple 14?

How do I write a loop to store a set of values for t and n(t) into an array?

 

I wrote a loop to get the values:

>for t  from 1 by 1 to 25  do print(t, f(t)) end do

 

but don't even know where to begin with putting them into an array.

Thanks for any help.

why dont any of maples 11, 12, or 13 work properly in windows seven? for example: when i click on "open a file" or "save" botton, and then it opens a window, the respective window dont show "up one level" or "create new folder" and "details" bottons above it.

Hi,

This is a student portfolio attached below. When I open the file, it says that "There were problems during the loading process. Your worksheet may be incomplete." The first time it happened, all of the graphs became blank, and the second time, only a portion of the worksheet shows up. Is there any way to retrieve the file?

Thank you...

Is it possible to set an external image-file as background in a 2d plot?
 

I am trying to define a function in terms of a solution of dsolve. I initially tried the following method:

I defined my function as:
a := 10; ode := diff( n(t), t ) + a*n(t);

Then I solve it using dsolve and store it as a function:
f:= t -> dsolve( ode, n(0) = 10);

This was syntactically wrong so I tried:
f:= t-> rhs( dsolve( ode, n(0) = 10) );

 

 How do I implement this sum in maple:

Sum(A[i,j],i=1..12) with j<>i

Gracias

 

 

This is what I have so far

S1:=unapply(u*FresnelS(u)+((1/Pi)*cos((1/2)*Pi*u^2))-(1/Pi),u);

C1:=unapply(u*FresnelC(u)-((1/Pi)*sin((1/2)*Pi*u^2)),u);

with(plottools);

with(plots);

u0:=sqrt(0.25);

e1:=evalf(FresnelC(u0)+FresnelS(u0)*cot((3*Pi)/8));

p1:=display(plot([FresnelC(u),FresnelS(u),u=0..u0]));

p2:=display(plot(x-e1,x=0..1,y=0..1,colour=black));

display(p1,p2);

 

I find that Maple leaves things like sin^2(x) + cos^2(x) as they are, which is giving me some very long and complicated looking expressions that are often just simple things.

I'm sure there must be a way of sorting this out but I can't find anything.

Also, on a more theorectical note, does anyone know why Maple doesn't do this automatically, or at least have a pre-programmed command to simplify such things?

Hi

How can add the values of a list with the list as an argument of a function. As exmaple:

f([1,2,3,4,5]);

Hi. I have a function F as follows: F := 1/16*sin(Pi*cos(h))^2*sin(Pi*sin(h))^2/cos(1/2*Pi*cos(h))^2/cos(1/2*Pi*sin(h))^2; It has a maximum in the interval 0..Pi/2 at Pi/4. If I do: Fder := diff(F, h); solve(Fder, h); > (1/2)*Pi, -(1/2)*Pi, 0, Pi the solution Pi/4 is missing from the set returned by solve, and solve does not even issue a warning about the incomplete solution set. Surely Pi/4 is a solution, as you can find it visually: plot(F, 0..Pi/2); and also numerically: fsolve(Fder, h=Pi/4+0.1); > (1/4)*Pi

How do I specify curly braces in the argument of \maple*?

I tried them as single characters, then they are gone after the Latex run.

When I try \{ ... \} instead, then the latex2qu run gets a stack overflow.

I can write square brackets instead and replace them in the .qu file, but that's very inconvenient.

Or is it a general necessity when you write your questions using Latex, that you have to edit the .qu file for similar shortcomings?
