Is there a simple way to reverse the handedness of the axes? I have the following figure:

shadebetween(0, 2-x-y, x = 0 .. 1, y = x^2 .. sqrt(x), scaling = unconstrained, color = yellow, axes = normal, labels = [Z, Y, X], transparency = .9)

and I want the X and Y-axes reversed from a left-handed orientation to a right-handed orientation.

I recently changed to a very high resolution monitor. The worksheet material is fine, since I can control the  zoom level, but the material at the top panel, the menus and information in the help page panels is much too small,  How can it be controlled?

Thank you,                        --Micha Hofri

Comment:   The responder tomleslie indeed identified the problem --- fixed pixel-count programming  Some software products, such as the FireFox browser provide access to hundreds of configuration parameters.  Surely the Maple tools have such a file, but I have seen no access.

The monitor I use is indeed of high resolution, the manufacturer says it is 3840x2160, (24'' -- I use 2 of them in a T configuration).  It is a delight, except when trying to read minute characters.

I suppose I need a pointer from the people in the know........Micha Hofri

Responding to a comment by Mac Dude that the issue may have to do with Windows.  I assume he refers to the MIcroSoft OS.

My computers run the Mint distribution of linux (window manager is Mate).  These matters are important, yet my needs would likely be addressed by the Maple user interface mechanisms.

My difficulty is finding a way to interact with these mechanisms, I suppose.   --Micha Hofri

g3 := 2*(1+exp(4*x))/(exp(4*x)-1);
a:=eval(diff(g3,x$n)/n!, x=0) assuming n>=0:
hello := sum(a*x^n, n=0..infinity):

it run a very long time like endless
 

please see the attached worksheet and assist me with understanding why these unusual results are computed.

Hello fellow Maple users

I am having trouble with the following integral:

I would like Maple to return the following answer:

I hope there is someone out there who can help me with this issue.

Hello everybody.

I'd like to share an observation about the integration of the Jacobi elliptic functions, in particularly the elliptic sine sn(x,k).

It's correct answer. But when I make the integration of the expression

according to the Handbook of Elliptic Integrals for Engineers and Scientists we have slightly another result

What is the difference?

when use cmaple and print command to show result in text file, it use multiple line to express

but not maple command

how to print the maple command instead of multiple line expression when use cmaple

g2 := arctanh((exp(2*y)+sqrt((exp(2*y))^2+exp(2*y)))/exp(2*y)-1)-1;
singular(g2);
FunctionAdvisor(definition, g2);
plot(g2, y=-5..5);
 

Hello,

I would like to build a Maple call, whereby 5x^3+7x^2+2x^3 is somehow exported to latex without collecting like terms.

I cannot seem to get it to work.

any help would be much appreciated.

Thanks,

Mark

Is there an iterative solver for numeric equations. I'm trying to solve for Iarc & Rarc knowing C and Z1, Z1 can be complex.

Dears,

I have seen a Mathematica code which I would like to have it in Maple, since I do not know that program. Let f(z) an analytic function, say f(z):=1+2^{z+1}+3^{z}. To find the roots of f(z) in a regingion, we can use in Maple the command "Analytic" (of the package "RootFinding"). However, in Mathematica is used the following:

L = 20; Monitor[zeros = Flatten@Table[N[z /. Solve[f[z] ⩵ 0 && k L ≤ Re[z] ≤ k L + L && -10 < Im[z] < 10, z], 25],{k, 300}],k];

What means the "N[z/. Solve..." instruction? Also, the following command:

SortBy[zeros, Re]; 

Can be "translated" to Maple?

Many thaks in advance for your comments!

With Regards,

G.

I run two small computations to test the improvement that should occur when using several cores (8 cores in my computer):

N:=100000.:

st:=time():

w:=seq(sqrt(i),i=1. ..N):

time()-st;

and:

with(Threads):

st:=time():

w:=Seq(sqrt(i),i=1. .. N):

time()-st;

And the results are: 23.6 sec with seq, and 118.4 sec with Seq!

Seriously?

How can these results be explained?

Thank you in advance

I do long "for loops" which perform the same procedure with different inputs and collect the outputs in a vector. In Matlab I use the command "parfor" to accelerate the calculations.

What is the equivalent of "parfor" in Maple? 

An example would be useful.

Thank You

hey everyone
i got a little problem here i really dont get it why my fsolve give me this error

why i cant get the awenser and if you can plz solve it for me

i would be happy that anyone can give me an explanation with details

tnX a lot
