Hello,
I have some variables which usually have a specific value. I also have some parameters which are calculated using the previously mentioned constants. Sometimes though I want to change the value of the constants and re-calculate the parameters. Therefore I created a library with the initial values of the constants which I load inside a procedure which calculates the parameters. That way I can change the value of the constants and the initial values are not overwritten. My problem is that I want to export the calculated parameters and the value of the constants at the specific calculation. How do I do that_ I don't have an array, table or anything like that. Should I put my parameters in a table?

Thank you for your time.

Hi guys,

I am trying to solve for the roots in a polynomial of infinite order. The idea is simply to approximate the infinite polynomial by a high order Taylor expansion, solve for the roots in this polynomial (both real and complex roots exists) and use these roots as initial guesses for finding the authentic roots of the infinite polynomial in this specific range.

I have tried to use the evalf(RootOf(PolyInfinite=0,x,Re + Im)), however the output from RootOf seems to converge to the same 2 or 3 roots almost independent of the initial guess. Is there specific options of this RootOf function that can stabilize the solution or another/better command to use?

On the other hand i could solve this by simply minimizing a least sqaure, however i have not found any optimization solver which supports solutions in the complex domain?

I sincerely hope that you are able to help me.

Kind regards

Lasse

in maple 12

solve(a*b+a*c, [a(t), b(t), c(t)])

it return []

how to convert to a parametric form 

and then integrate them, 

and then convert parametric form back to f(a,b,c) ?

for base 10

1 op1 5 = 

        01

op1   12

_________

first digit of first number 1     = 1

first digit of second number 1 = 2

 then find 12 in logic table, it is 1, separation is 1 means move the value 1

to left 1 digit become 10

convert 10 back from base 3 to base 10, it is 3

how to construct this unknown name operator table with the custom logic table Min, Except, Diff

based on the operation described

no matter the logic table is correct or not, hope to mechanize these calculation steps for developing 3 operation table for base 10 quickly.

is it possible to develop a new kind of algebra with 3 new operators with the use of 3 operation table?

Hey, everyone!

Given the following equation: 

 I need to plot the graph when x₁ = 0.4.. How can I do that?

I managed to plot f(x) just fine, just not sure how to plot Newton'sMethod at x₁ = 0.4.

Thanks in advance! :)

E=0   f(E)=1.8  = 1/A+1    A=-0.444    kt is unknown. Hence I try many numbers.

This is my code

plot(1/(-0.444*exp(x/3)+1),x=0..9);

I have a problem.  A is negative. The denominator would be zero.

This is the theory.

If I type in a function in 2D Math, the text disappears. for example, if I type fsolve(), until fsolve, the text appears, but after i type (, the whole text disappears. How should I solve this? Thanks.

Hello,

I am very new to programming and currently i am taking a course in numerical methods which allows me to get some exercise programming mathematical functions using maple. I am trying to plot a graph and it gives me an error. If anyone can guide me i would really appreciate it.

Also if there are any helpful advise for me to start using this language, it would be a big help.

Thank you

Just got Maple 18 on academic license. I've used Maple 15, 16 and 17 before this.

It wont write simple math symbols as + - * and := 

I have tried both document- and worksheet, reinstalling and so on...

What is the problem?

Thanks

I am running under Windows 7 and using the following command in a MAPLE .mw file to convert a group of .mw files to WWW format:

MapleWWWW:-Install("S:/MRBwork/Phd/SOFTWARE/MAPLE/R4&5/Conversions to MAPLE WWW/Input/","S:/MRBwork/Phd/SOFTWARE/MAPLE/R4&5/Conversions to MAPLE WWW/Output/","http://digi-area.com/light/MapleWWW/js/maple-www.js");
Error: FileTools:-Text:-ReadFile("file or directory does not exist: %1")
Error: FileTools:-Text:-ReadFile("file or directory does not exist: %1")

As you can see I am getting an error return. I believe I have placed the module in the right directory. As a test I ran the following:

FileTools[IsReadable]("S:/MRBwork/Phd/SOFTWARE/MAPLE/R4&5/Conversions to MAPLE WWW/Input/"); FileTools[IsReadable]("S:/MRBwork/Phd/SOFTWARE/MAPLE/R4&5/Conversions to MAPLE WWW/Output/");
true
true

So both folders are recognised by MAPLE.

Can anyone help debug this please?

Attached is my sheet.

On my system if just execute the whole worksheet maple return the last statement's integral un evaluated, however at this point if re-execute the statements from the definition of L2, it looks that maple has evaluated the last statement's integral.

What am I missing here, any help?

Regards!!

Consider the following two variable funtion:

f(x,y)=x^2+y^2-5

then we want to draw a contourplot:

contourplot(f,x=-10..10,y=-10..100)

My problem is that I want maple to diplay the value of the function "f" relating to each curve on the contour plot!
How can I do this?

Please see the following code.

I am using Maple 12 in Win 64. I have some difficulties in evaluating expressions in Maple. For example simply writing cos(x) then differentiating it w.r.t x. After writing cos(x) in 2D Math mode, I do right click for selecting diff but it does not work. The pointer turns in to busy mode and nothing comes to select. Also, I tried this operation in the tutorial file teaching differentiation, however problem persists.
