I have recently install Maple17 on my computer (Windows10) and I need to use some Greece alphabet such as ß but I look everywhere in maple's icon and I just could find capital Greece alphabet.

does anybody know how can I find those?


Hello i want to solve the differential equation but i have these problem i don't understand  why !?


Euler_x := -(diff(lambda3(t), t)) = 0;
Euler_y := -(diff(lambda4(t), t)) = 0;
Euler_Vx := -lambda3(t)-(diff(lambda1(t), t)) = 0;
Euler_Vy := -lambda4(t)-(diff(lambda2(t), t)) = 0;
Euler_theta := lambda1(t)*sin(theta)-lambda2(t)*cos(theta) = 0;


sys:={Euler_x, Euler_Vx, Euler_y, Euler_Vy, theta=arctan(lambda2(t)/lambda1(t)), diff(Vx(t),t)=Vt*cos(theta), diff(Vy(t),t)=Vt*sin(theta)-g, diff(y(t),t)=Vy(t), diff(x(t),t)=Vx(t),x(0)=0, y(0)=0.302, lambda1(0)=0, lambda2(0)=0, lambda3(0)=0, lambda4(0)=0,transversalnost, x(176)=120};

ans:=dsolve(sys, numeric, output=listprocedure):

Error, (in dsolve/numeric/bvp/convertsys) unable to convert to an explicit first-order system

thanks for your help



I'm trying to write the cumulative distribution function into maple but I seem to get an error. The code is:




I get an error message "Error, (in Statistics:-CDF) unexpected parameters: inert = true".

It used to work, maybe because I was using a newer version of Maple.

Hey guys,

I have a problem with this code:

d := Array(1 .. 15);

for i to s1 do

for c2 to 15 do

if `mod`(c2+(J+H)*(`mod`(1/(H+1), A[i])), A[i]) = 0 then d[c2] := d[c2]+l(A[i]) else d[c2] := d[c2]end if

end do

end do;


The problem is that my code stops running when I encounter that `mod`(1/(H+1), A[i]) doesn`t have an modular inverse. What I would like to have is that the loop just continues and does nothing when my array when it encounters an error.

Hope you can help me!

Could you tell me what the maple player is ?

Hi MaplePrime-ers,

I'm using Maple17 in Matlab 2012b to evaluate a symbolic function over a grid of values.  The number of values is generally ~500k, and therefore I have a loop that dumps the solutions into MATLAB where the values are parsed and stored more efficiently.

I put this proceess in an optimization routine, and I keep getting crashes.  The crashes are NOT repeatable.  They generally happen after 4-10 times the routine has been called.  

This is one of the stack dumps.  Anybody have any ideas?  I talked to MATLAB support, but they weren't very useful (they started pointing fingers).

¿como puedo resolver problemas en maple17?  

I am trying to use Maple to produce an image that will be part of a math paper.  The final image must be in .eps format.  Whenever I produce a plot in Maple17 and click on it, it looks like the image has the shape of a square (regardless of what's inside it), perhaps with a lot of empty space.  I want an image without a lot of empty space, and I'd like Maple to do this.  If I crop a square image using some other application, it is not going to improve the quality of the image and might hurt it.  

If the answer to question in the Title is "no", can anyone suggest a good way to produce a good .eps image from a Maple plot that is cropped properly to eliminate as much empty space as possible?  I have Photoshop, but I don't know if this is the best way to go.

I wrote a toy file that plots a simple curve.  I'll upload it and provide a link to it.  If you execute the code and click on the image, you'll see that it is a square with a lot of empty space.












according to this page

it says "Maple 17 features a completely new editor for writing Maple code."  but for the last 15 minutes I've been looking in my Maple 17.02 for windows and not able to figure where this editor is or how to start it.

When I open Maple, I say File->New-> and nothing there for an editor.

I also looked in my Maple installation icons group, there is nothing there.

I also looked here

"Maple 17 features a completely new editor for writing Maple code.   The editor includes many features to make it easier to write, read, and debug Maple code, such as syntax highlighting, bracket matching, command completion, and automatic indenting. The new editor is available for managing startup code, inline code edit regions, and code attached to embedded components."

but again, does not say anything about how to START it ? Or is this editor a separate apps I need to buy?


I have located a claimed webpage that shows Advanpix doing sparse matricies much faster than Maple.

The slowness is usually the result of poor coding or someone not well versed in Maple software. 

Anyone care to comment on the times?  I am sure the presented code there can be improved.

I want to be able to check an answer using Maple. Say perhaps I have a question such as "Find d,e,f such that f(x)=dx2+ex+f has the properties f(0)=4, f(3)=7, f(-2)=18".

The question is completely theoretical as I don't want to use the same question that I have been given myself and be accused of cheating, maybe the particular features that I have chosen are completely absurd.

My question is how would I go about using Maple to find/check that I have the correct values of d,e and f?

The exercise is as follows:

"Write a looping structure that finds the four substrings (of a string assigned to the nameMyString) containing only lowercase letters, uppercase letters, decimal digits, and specialcharacters."


I'm a bit lost with this one, I can find the substrings they asked for but why make it a looping structure?

Exercise description: "Find the product of the square root of all prime numbers less than 100."


I'm very new to maple, and I'm having problems with this exercise.


I've managed to write a script that'll give me the prime numbers, but I don't know how to get the numbers into a format I can work with.


My script:


for i to 100 do

if isprime(i)=true then


end if

I am currently running sucessfully Maple 15 on Macbookpro mid 2009 4G, CPU 2,53 Ghz Intel core duo, NVIDIA GeForce 9400M 256 Mo, OSX 10.8.4

I bought the upgrade to Maple 17, when launching the install package : I have a grey window with a "next" button with slow flashing : impossible to click on it ... so impossible to install the new version

thanks for your help !!

by the way Java installed

best regards


Try to run the following:

>d := conjugate(u)*conjugate(y)+conjugate(v)*conjugate(x);
>z := conjugate(f)/d+conjugate(G)*w*conjugate(w)*conjugate(y)/d;
>z2 := simplify(z);

and you will get correct answer
