I have a procedure that gets two lists A and B, I want to restore the name of the entry lists as string. How can I do that?

 

f(A,B) [procedure]

e.g. a(MyList,LL)

 

I want to restore a:="MyList" and b="LL"

 

TIA

Hi:

I am trying to use the Physics package to help me deal with non-commuting operators, but having some problems when trying to simplify expressions.The following should explain what i mean:

 

################

restart:
with(Physics):
# 'a' represents a quantum operator
Physics[Setup](noncommutativeprefix={a}, mathematicalnotation = true);

#we can try to expand to see that a and Dagger(a) do not commute!
expand((2*a+Dagger(a))^2);

I should convert factors of a generic equation into standard form (scientific notation) :

 

 example_eq := 345.1234 x1(t) + 34.5691 u1(t) - 5423.8932 y1(t) + ... many other terms...


Is there some maple command or procedure to convert automatically every factor of a generic (very long)   equation ?

 

Manipulating a system of long equations maple gave in output the following error message:

1. can it have simple solution for convert(taylor(Qx*exp(z), z=0,5), ratpoly); as my solution have     hypergeom([-1/2i, ....?

    for example where Qx = x/m, if m is also increasing from 0 to 5 by one in each term

    How to write these command?

    is it sum(Qx*z^m/m!, m=0..infinity); but convert this result to ratpoly result in error, if exp, it will have summation,

 

Hi im somehow not able to export my worksheet into a word document, as the rtf format doesnt seem to be available on the maple 15 mac version. converting into html is possible but not satisfying. i really need help here.

thanks a lot !!!!

greetings

Hi,

I am trying to simplify the expression s as given below. (I am not sure why it comes up with all the vector caclulus notation in it but it should display okay when you enter it)

Because of the presence of the exponential imaginary fucntions I thought evalc might be useful but when I use it I get a huge expression with csgn appearing in it. To my knowledge csgn appears when assumptions are not correctly specified - is this so? I can't see any assumption...

I've been using LagrangeMultipliers to solve a problem. Solutions returned involve RootOf.

What I want to do is extract the expression within RootOf() so that I can do fsolve() on that.

The expr from RootOf is a 6th order polynomial in _Z.

I've tried convert(RootOf(...), radical), but it doesn't work very well on polyhnomials of order greater than or equal 5.

Any suggestion(s) for this extraction that I want ?

I need to send a Maple worksheet (.mw) to someone who is not a Maple user,doesn't have Maple installed.So what is the simplest possible solution now?How can I convert this into a pdf/doc/ps/eps  file so that any document viewer can open it?

A problem with convert,StandardFunctions

 

P := hypergeom([-k,1/2-k],[-2*k],1-z^2);

(1)

convert(P,StandardFunctions);
P1a:=subs(k=1,%);

 

(2)

P1:=subs(k=1,P);

(3)

plot({P1,P1a},z=-1..1,0..2);

 

convert(P,StandardFunctions) assuming k::posint;

(4)

How to get the polynomial successfully why return error expect a series valuation 1, what do it mean?

l := [12,14,27,35,46,49];
sl := listtoseries(l,x,revogf);
convert(sl,ratpoly);

 

any of the numerical factors that multiply the successive terms in the expansion of an expression of the form  (x + a)^n,  for integral n,  in accordance with the binomial  theorem. These are any terms of the form
               ∑x^(n-k)*a^k*binomial(n,k)


how to get it.

convert((x+a)^n,Sum,x)


but ,i get a anwer that i don't want

How to join expressions?...

How to join expressions in the set, for example to convert the set {y=0, x>-1, x<1} to {y=0, -1< x <1}?

Thank you in advance.

I am using dsolve(..., type = series) to solve differential equations in the form of a power series. I plot these power series with different orders to observe how they converge. I use quite large orders (25 or even 50), and generating these solutions is slow.

I would like to generate power series with order 25, for example, and then truncate it to order 24 directly, instead of having to call dsolve a second time. I was hoping this could be done somehow using convert...

Hello

I tried to modelise the move of a pendulum. I have this equation:

eq := (1/2)*m*((l+r)^2+(1/5)*r^2)*(diff(theta(t), t))^2-m*g*(l+r)*(cos(theta(t))+cos(angleInitial)) = 0;

 

I tried this programme:

pend := proc (a0, l, r, m,nbpoints)
local eq, sol, valeurstheta, x, y, plotseq, g;
g := 9.81;
eq := (1/2)*m*((l+r)^2+(1/5)*r^2)*(diff(theta(t), t))^2-m*g*(l+r)*(cos(theta(t))+cos(angleInitial)) = 0;
sol := dsolve({theta(0...
