Thanks,

However, this does not work.

My problem is not to plot U as a function of time, but somehow convert the function.

I mean, in Your solution U is defined through X(t) and thus Maple is evaluating the solution for DE every time the U is called.

However I would like to have U as function of t without precense of X(t). Since X(t) is a known procedure, there might be the way to explicitly define U as a function of t only, after the evlauation of procedure X(t).

Hello,

I have four old Maple 10 Worksheets sitting around my harddrive. I'd like to view them again, but my Maple 10 license won't be activated again, they tell me to buy a new 13 or 14 one.

Does anyone still have a Maple 10 (or compatible) version and would convert four small worksheets into PDF for me?

Thanks!

Hey there, this is my first post here, so hello to everyone.

I have (so far) one question. I have a circle equation like

x^{2}+y^{2}-6y+6=0

I know, that on a paper, I can convert it to the "normal" circle equation, from which I can read the middle point and radius of the circle. And now my question is, how to convert in in maple? I am using the 11th version.

I have tried solving this equation and (x-a)

Hi there

I have, for a while, been trying to find a way to force maple to display the unit im inputting.

Im studying to be an engineer, and for an example the unit i often would like displayed is kilonewtons per square metre (kN/m2).

Once i hit enter, maple converts it to Pa, which isnt really usable for me ...

The question is, is there any way to stop maple from doing the conversion in output......

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);

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

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

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

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