If I insert a hyperlink to a website, it works fine when I'm in Maple, but when I export my Maple to pdf, the hyperlink is not clickable anymore.

I've tried using both Windows' "Microsoft Print to PDF", Maple's own "Export to PDF", "cutepdf" as well as MacOS "Save to PDF". Is there a way of doing this?

Best wishes

Hey any one can help? I calculated the characteristical Polynom of my Matrix M:

-(lambda-2)^2*(544-lambda^9-328*lambda^7-16*cos(x-y)+6*cos(x-y)*lambda+6*cos(x+y)*lambda-408*cos(y)*lambda^2-408*cos(x)*lambda^2+540*cos(y)*lambda+540*cos(x)*lambda-28*cos(y)*lambda^4-28*cos(x)*lambda^4+152*cos(y)*lambda^3+152*cos(x)*lambda^3+2*cos(y)*lambda^5+2*cos(x)*lambda^5-256*cos(y)+17232*lambda^2-256*cos(x)-7852*lambda^5+17768*lambda^4+2088*lambda^6+28*lambda^8-16*cos(x+y)-23632*lambda^3-5844*lambda)

now I want to solve the second part of the polynomial with lambda^9 but maple gives me the RootOf-function

_Z^9-28*_Z^8+328*_Z^7-2088*_Z^6+(-2*cos(y)-2*cos(x)+7852)*_Z^5+(28*cos(y)+28*cos(x)-17768)*_Z^4+(-152*cos(y)-152*cos(x)+23632)*_Z^3+(408*cos(y)+408*cos(x)-17232)*_Z^2+(-12*cos(x)*cos(y)-540*cos(y)-540*cos(x)+5844)*_Z+32*cos(x)*cos(y)+256*cos(y)+256*cos(x)-544

How can I simplify this expression to solve over lambda.

purpose is to plot all the eigenvalues.

Thank you in advance.

Hello,

Why does the following work as expected...

f__c := proc (x__0, y__0) options operator, arrow; piecewise(x__0^2+y__0^2 <= 1 and (x__0-1)^2+y__0^2 <= 1 and x__0^2+(y__0-1)^2 <= 1 and (x__0-1)^2+(y__0-1)^2 <= 1, 1, not (x__0^2+y__0^2 <= 1 and (x__0-1)^2+y__0^2 <= 1 and x__0^2+(y__0-1)^2 <= 1 and (x__0-1)^2+(y__0-1)^2 <= 1), 0) end proc

But the following does not?

cnd := x__0^2+y__0^2 <= 1 and (x__0-1)^2+y__0^2 <= 1 and x__0^2+(y__0-1)^2 <= 1 and (x__0-1)^2+(y__0-1)^2 <= 1
f__c := proc (x__0, y__0) options operator, arrow; piecewise(cnd, 1, not cnd, 0) end proc

(Sorry about the lack of formatting, the forum insists my Maple syntax is invalid)

The first one produces the expected result, x__0 and y__0 are treated as variables in the condition (i.e. f__c(a, b) returns the same piecewise function with x__0 replaced with a and y__0 replaced with b); the second one does not (i.e. f__c(a, b) returns the piecewise function, still with x__0 and y__0 in the condition, and never gets evaluated).

Dear all

I have a system of PDes, the code i think it's well writte but when I use pdesolve i have no solution obtained.

Maybe I must add something else

Many thinks

I am defining, 

f(x):= x-> diff(g(x),x)/(1+g(x))

Here g(x)<<1 and I am looking for series expansion, 1/(1+g(x)) = 1- g(x) + g(x)^2 etc.

But I cannot get this by using series(f(x),g(x)=0) or other options.

Thanks,

Rahul

Is there a way to remove the parentheses around y'(t)?

Thank you!

Why doesn't the second nested procedure keep a unevaluated?

With Typesetting level set to Maple Standard, x->(f@g)(x) is displayed as x->f@g(x), which is wrong because composition has lower precedence than function application.

sum((-1)^k/k^(1/2), k = 2 .. infinity);

how can filter data im maple 18 befor used in draw plot? i need simple example

this is plot of f(x)=x² (by used maple18) ,how can me change (2.5-, 1.5- ,0.5-) in x-axis to true?

Anybody know how to compute coding for eigenvalues for basic reproduction number using the next generation matrix?

I dont know how to compute coding for eigenvalues.

Hello people in mapleprimes,

I have a question.
I want to modify

a := rho^(epsilon-1)*a__01^(-k)*(N__E2/Omega+N__E1*mu)*(K+1)/mu;
to
b:=rho^(epsilon-1)*a__01^(-k)*(N__E2/(Omega*mu)+N__E1)*(K+1);

But, I can't do that modification.

The key term is
c:=N__E2/Omega+N__E1*mu;

I know how to use applyop, but even if I use it, I couldn't obtain b.

Please teach me about this.

Hello everyone!

Total beginner here. So far I am just using the right click options in Maple,  and worked wonderfully until now.

Two questions for some charitable sould out there:

1) I have a system of inequalities that I need to solve. I am interested in the *conditions between the variables under which a given inequality is satisfied*.

Using the "solve" command I only get a few of these. Do you know any script that can obtain more solutions? 

2) I have some (long) equations and want to be able to visualize them in different ways to make sense of it. So far I have only been using "simplify" and "combine", but it keeps on returning the same result even if I can see there are other possible ways of factoring the equation. How can I tell Maple to give me "different optiosn" as to visualize the equation?

Thank you all!!

Hi there,

I am doing my assignment and struggling to do the last question: (only part (c))
code: Qmaple.mw
The left side shows the question. 3(d) is basically a phase portrait / vector field plot of a 2D system of differential equations on x-y plane. However,I am not sure how to extend it to 3 dimension. Moreover, for the second part, they ask me to plot x-t and y-t on the same graph,which is something similar to right hand side of the above picture (NOTE:THE plot doesn't represent the system in Question 4) . However,I've got the z term.How should I fix it?
