MaplePrimes Questions

Hi there,

I have the following complex-valued function,in polar coordinates:

Gamma is an arbitrary real constant.

How can a generate a 2D plot of w(z) using maple? 

Thanks!

Dearz 

I want to ask how to run multiple program at a time in maple? I am waiting your positive response. 

Is it possible to print/display a hyperlink within a worksheet (programatically, not by clicking menu)?

For example:

Software:="Maple";  # URL:=www.maplesoft.com

so it outputs:

Hello,

I have a problem with graph using odeplot.

As showed in lower picture, the value of the y axis is so long.

So, i want to adjust the display digits to decrease the length of the values.

Do you have any method to do it?

Thank you!

 

I would like to check if op(n,g) exists for a given function g and a positive integer n.
How do I do it?
Naturally, I don't have the function g. It is theoretically created.
Thank you!

How do I solve a differential equation in Maple?"

Hello!

How can I make a list containing all inequalities
A[i,j] >=0 where A is a nxm-matrix?

This works, but si laborious:
[(A[i,1]>=0)$i=1..3,(A[i,2]>=0)$i=1..3,(A[i,3]>=0)$i=1..3];

works, but result is nested:
[[(A[i,j]>=0)$i=1..3]$j=1..3];

should work, but doesn't - why?
[((A[i,j]>=0)$i=1..3)$j=1..3];

Thanks in advance

Hi,

Not sure if I'm just being a bit daft but I'm struggling to obtain the correct solution to the following...

If we have the following:

And I enter the following into Maple:

Which I believe to be correct.  When I try to use p within the limit function, I cannot seem to get the answer 2 ?

 

What am I doing wrong here?  It's driving my bonkers!

 

Thankyou.

Hi,

I have an inverse I solved for with RootOf, which I transfrom and then try to numerically integrate the transformation. I get the following error: Error, (in convert/radical) too many levels of recursion

Integrating the inverse itself works, it is after applying the transformation 1/(1+x2) that I get the issue. Eventually I want to integrate something less simple, but here the problem already starts. 

Thanks for the help! Its for science! 
 

g1_inveq := proc (t, x, alp) options operator, arrow; tan((x-t)/(alp*(1+t^2)))-t end proc

proc (t, x, alp) options operator, arrow; tan((x-t)/(alp*(1+t^2)))-t end proc

(1)

g1_inv := proc (v, alp) options operator, arrow; evalf(RootOf(g1_inveq(t, v, alp) = 0, t, 1)) end proc

proc (v, alp) options operator, arrow; evalf(RootOf(g1_inveq(t, v, alp) = 0, t, 1)) end proc

(2)

evalf(Int(1/(1+g1_inv(v1, .5)^2), v1 = 0 .. 1))

Error, (in convert/radical) too many levels of recursion

Hey all together,

this is my first question in this community and it is maybe a very simple one:

If I have a given matrix. How can I process individual elements with an mathmatical operation?

For example, I have a diagonal matrix and want to get a matrix in which every non-zero element is the square root of the inverse of its former element.

Has someone an idea?

Thank you very much!

hello , there , i want ask a Question ,

i have a vector result n hier , and there is a long part with ^1/2 (like unter) , which is not defined before , just from compute ,i want to replace this part with A, and have tried to use subs , but it didnt work . 

And i have tried to define it before compute, and then use subs , aber it also didnt work .

so how can i replace or define this part in the result?

thanks

 

Dearz

I draw multiple graphs in singal coordinate with same line style. I don't know how to change the line style and color for g[1], g[2] and g[3] becuase of loop. Please some fix my problem to give them different style and color.

Maple function code:

GetAngle := proc(opp, hyp)
local theta;
theta = arcsin(opp/hyp);
evalf(180/Pi*theta);
end proc:
GetAngle(4,5)
                       57.29577950 theta

Matlab code:

function [outputArg1,outputArg2] = GetAngle(opp,hyp)
    theta = asin(opp/hyp);
    outputArg1 = 180/pi*theta;
end

> GetAngle(4,5)

ans =

   53.1301

Ditto same code from Maple programming guide 2017:

 

Why is there a difference in the answer, am I coding it wrong? I mean any syntax errors that I am not following?

I need find CPU time for a set of mathematical calculations,  what is the best method in maple 18?
