I posted this question on the Newbie Forum without success, so I thought I should go ahead and post it here, too. My problem is simple algebra (except there is a lot of it). Every function involved is real, though I'm not sure exactly how to tell Maple that. The equation involves a term under a radical, which I think is the cause of my difficulties. To deal with the radical I use a the simplify/radical command, and I discover that the remaining radical exists in only one term. So I isolate that term on one side of the equation and square the equation. Then I discover that the variable I want to solve for is a common factor, and it appears in even powers. I do a subsitution and end up with a quadratic equation which I solve using the quadratic formula. When I plug the solutions back into the squared equation, I find that they correctly solve that form of the equation. However, when I plug them back into the original equation, I get a mess that I can't seem to simplify. I could use any help you can offer. I will attach a worksheet containing the relevant parts of my work here(with the messiest stuff removed).

hi my name is john.i just purchased maple last night and can't figure out how to use it can somebody help me do this questions using maple?this are the questions.i need to evaluate this four question.thanks! > int(x/(x^4+9), x = -infinity .. infinity); > int(1/(x-8)^2/3 ,x= -infinity..0); > int(x/sqrt(4-x^2), x= -2..0); > int(1/1-cos(x), x= 0..Pi);

hi!i tried using the limit tutor for the ff questions but it just said "no rule is applicable for this problem" please help me i dont know what to do..thanks!i appreciate it. > 1.) (lim)(sqrt(x-1)-2)/(x^(2)-25); > x approaches 5 > 2.) (lim)(x+1-(e)^(x))/(x^(3)); x approaches 0^+ > 3.) (lim)(x^(3/(2))+5x-4)/(x ln x); > x approaches infinity > 4.)

Hi: I have a complicated expression containing many Maple generated terms each of which typically looks like: 12/b/(b^s)*s/sin(Pi*b)^2*Pi^2 I absolutely can't figure out how to make 1/b/b^s become b^(s+1). I have tried using "patmatch", "match", "subs", "collect" and have now run out of ideas. For example: subs(1/b/(b^s) = 1/b^(s+1),...) does nothing. Can someone please suggest a way to do this so that the end product will look like 12/b^(s+1)*s/sin(Pi*b)^2*Pi^2 Ultimately, I want to identify the exponents of b in each term. Thanks Mike

Hello all,

only occasionally using maple, I calculated some matrices and vectors numerically with maple and would like to use the output for further processing with other computer programs.

My problem is that the output format created per default is far from being machine readable:


[0. , -0.374388562686400750 10 , -0.374388562686400750 10 ,

-18 -18]
-0.174912303608013020 10 , -0.174912303608013020 10 ]

[ -18 -18
[0. , 0.708119543904595083 10 , 0.708119543904595083 10 ,

hi.how can i use maple to distinguish wether a series converges or diverges?thanks guys!

hi i am a new user of maple soft.can anybody please help me.i need to know how power series works with maple.thanks!

Hello,

Please help my with my program. First, I'll post the relevant code, then the questions:

--------------------------------------------------------------------------------------

with(Statistics); with(LinearAlgebra);

#k is a Vector everywhere in this program
ModeFreq := (k, m)->Norm(<Norm(k, 2), m>, 2);
OscillatorAmplitude :=(n, k, m, x) -> (ModeFreq(k, m)/Pi)^(1/4)*exp(-1/2*x^2*ModeFreq(k, m))*HermiteH(n, x*sqrt(ModeFreq(k, m)))/sqrt(2^n*factorial(n));
DeltaApproxAmplitude :=(x0, N, k, m, x) -> evalf(expand((sum(OscillatorAmplitude(n, k, m, x)*OscillatorAmplitude(n, k, m, x0), n = 1 .. N))/sqrt(sum(OscillatorAmplitude(n, k, m, x0)^2, n = 1 .. N))));

I am a newcomer to Maple, so I am going to assume that my problems are generally simple, and that I should be posting in this Newbie forum. My apologies in advance if I assumed wrong. My problem is that I take an equation that contains a radical as a common factor for several terms, rearrange it so the radical is on one side, square the equation to remove the radical, and then do a change of variables to convert the equation to a quadratic and solve it. All of that goes well, but when I convert back to the original variable and attempt to verify the solution it becomes very complicated, and I can't seem to simplify it enough to verify the solution.

This is a portion of my first Maple program. I included the part that had the relevant code and output of what is going wrong. The problem I am having is in the PlotTable I create. It is a table with specifically defined indices, which gets added to each time through a loop. What each indices refers to is a table of lists, representing an x,y coord pair. The first time an index is added is corrects puts the data. The second time you can see that it added the second data correctly, but it also overwrote the data for the previous index. for k from 1 to nops([indices(thicknesstable)]) do #loop for each structure

Hi! I'm wondering how I'd go about attaching multiple coefficients from a list to a function, while storing the output as a list. An example of a simple case (the only one which I've been able to get to work) is as follows: for j from 1 by 1 to 3 to f_j := j*sin(x) end do And then, when I want to manipulate the output, I have to handle each output element separately. I also know how to attach a list of coefficients from a list, but handling an expression like f_2*tan(23) = 2*tan(23)*x^2 is cumbersome and a bit silly, and not at all adequate for expressions with multiple terms.

I have to solve the nonlinear equation, i give the all indication, but the system also give the error to me. who can help me to solve this problem? my equation is : a[1]:=2:b[1]:=0.01:a[2]:=1:b[2]:=0.01: a[0]:=1:b[0]:=0.01:a[3]:=1:b[3]:=0.01:v:=0.2: RF:=diff(x[1](t),t)=a[0]+a[1]*x[1]+a[2]/(v-x[1])+a[3]*x[2]/(x[1]*(v-x[1])),diff(x[2](t),t)=b[0]+b[1]*x[1]+b[2]/(v+x[1])+b[3]*x[2]/(x[1]*(v-x[1])); > ic:=x[1](0)=5,D(x[1])(0)=0,x[2](0)=1,D(x[2])(0)=0;x[1]*0.2=x[2]; > dsolve({RF,ic},x[1](t),x[2](t),type=numeric); Error, (in dsolve/numeric/process_input) received more than one indication of the dependent vars [x[1](t), x[2](t)]

I've been at it a year, but this is my first attempt to write and use a package. I wrote a module with an exported package and tested it within the worksheet in which I wrote it. I defined the file path with _liblist and both the binary and the source file appeared where I wanted them. I cut and pasted the same path information in attempting to load the program. So I am wondering why it didn't load. I'm using Maple 10.03 on OS X 10.3.9. ********************************************** file "MyMatrices" ********************************************** MyMatrices := module() description "routines for matrices";

> with('ScientificConstants'); > GetElement('Na'); ... atomicweight = ([value = 22.989770, uncertainty = 2.*10^(6(, units = u]), ... So if I do the following, I expect 22.989770 (grams/mol) > evalf(Element('Na',atomicweight)); -26 3.817543727 10 What is happening here? Why does "atomicweight" mean one thing in one context and another in another? Cheers Geoff Russell

I am trying to familiarize myself with the functionality of the Maplet Builder, and I'm having some frustrating problems. Whenever I set a button to change the value of a MathML viewer, for the command, I use the statement MathML[Export](insert Maple statement here), and I receive an argument error. In addition, I was wondering if (while using the builder) there was a way to add some code that evaluates one or more Maple statements (i.e., variable definitions to be used by multiple Maplet components,etc.) that does not affect the value of any of the component properties. I'm used to using the GUI components in worksheet mode which seem to be more flexible in terms of programming actions for components (perhaps only because of my ignorance pertaining to the Maplet builder).
