hi, is there a way to change color of the page in Maple 18? in fact I am preparing my lectures using slideshow option and want to change the color instead of the default white.

Hi guys,

       I have the following Lagrange function. 

       (Note :w is the generalized co-cordinate.) 

       L := (diff(w(r, t), t, r))*v(r, t)

       ( I know

        If L =diff(w(t),t)*v(t)..... I can write EulerLagrange(L,t,w(t) but I dont know how to handle above function)

        Thanks in advance!!!

There was a command for torusknot(x,y,z),r,R.  Is it included in Maple 17? The index and help to do not list it.

Is there a newer version of a torus knot?

i asked it to show explanations

and got an solution about that, but it doesnt work in my Maple

i wanna know what do i wrong , why it`s not working right

I am having issues opening my final year project, it was working an hour ago and now it will not open. When I try to open the file it brings up a box title TEXT FORMAT CHOICE with the options: MAPLE TEXT, PLAIN TEXT, MAPLE INPUT and CANCEL.

This is all my work and I need it to complete my year.

Any help with how I can rectify this would be extremely helpful.

Many thanks

Some maple worksheets are created in other languages (spanish, german, french, russian, etc...) , I attempted to use google translate but it is a paid service.  There are alternate free translators however I can't seem to get any of them working using the URL package. 

I'm trying to send data to http://translation.babylon.com/english/to-spanish/

Using similar code from my previous question with google translate we end up with a huge mess and no embedded translations in the code. 

s := "The quick brown fox jumps over the lazy dog":
result := URL:-Get(StringTools:-FormatMessage("http://translation.babylon.com/english/to-spanish/", s));

Any suggestions?

Hi

When I use below cmmand within conditional statements or proc loops, It dosent work

How can I use a similar command to export plot as an Image with arbitrary format under any circumstances?

plotsetup(bmp, plotoutput = `Pic.bmp`, plotoptions = `height=400,width=400`); NCP; (NCP has a plot structure)

Hi

I am trying to optimize a 39, 1 MATLAB matrix, but cannot seem to get a result beyond a 6, 1 matrix. I am getting "Warning, cannot resolve types, reassigning t##'s type" where t## varies from each time I run it, and can show multiple of these warnings. It also says "Warning, cannot translate list".

I found a pretty similar problem posted here earlier, where the user "Carl Love" suggested to replace a command from the original code with

Matlab(
     subsop([-1,1]= J, eval([codegen:-optimize](tmp, tryhard), pow= `^`)),
     output = string, defaulttype = numeric
);

I was wondering what exactly this command does? Can I apply it to my code to solve my problem? It yielded a result that looks (on the surface) as an optimized code, but I don't feel completely comfortable using it without being certain.

What I have done is simply to replace Matlab(tmp, optimize) with the suggested code above. My code is attached. Thanks in advance for any help.

Hi,

I'm, trying to write a nested loop in maple, but I keep getting the Unterminated Loop error. I'm sure the solution is quite simple, but I haven't been able to find it. Any suggestions would be much appreciated. The loop looks like this:

i:=0:
di:=25:
n:=1:  

while (n<=nLimit) do
sol1:=fsolve(eq1, y=i..i+di)
     if type(sol1, numeric) = true then
     lambda(n) :=sol1
     i:=i+di
     n:=n+1
     else  i:=i+di
     end if:
end do:

Just wonder if there is a way to have maplesoft.com not think I'm in Germany. On my computer, iPad, and iPhone the website reverts to German language. My locale is west coast US. And I often search the website to learn more about using Maple. 

It's not a big issue, but if there is a way to have it remember English, I'd like to know.

Cheers, all !

hello everyone..

please...

I need help to write a code to calculate the riemann sum approximation of the curve cos(sqrt(x^2+y^2)+1 

calculate the actual volume using integration

use the ranges x=[-2pi to 2pi]=y, and 20 subdivisions.

also display the curve and the parallelepiped approximations on the same plot.

Thank you for your help!

hi everyone,

i need help to write a maple code to generate an animation sequence showing the taylor series approximation of tan(x) from 

N=1..5.

plot the animation from x=-2pi to 2pi and y=-5 to 5.

thank you for your help..

hi everyone,

I need help writing a maple code to calculate the normal to the curve X^2-2X at x=1

and also display the curve, the tangent, and the normal on the same plot in the range x=[-2,2].

thank you for your help!

is it possible to use an animated zoom on a pointplot?

I used the view option (view = [-t .. t, -t .. t]) and animated the t value in a sequence, but it did not work.

kind regards,

Harry Garst
