I wan`t use maple to solve my problem

x1[n]= ej*( Π/6) *n

Hey, so i guess i dont really know whats going on. I am trying to install Maple 10 on my Macbook Pro. I get an error message Uncaught exception in main method: java.lang.NoClassDefFoundError: org/apache/crimson/parser/XMLReaderImpl when i try to open the program. Any help?

Want to do smth like that:

Call EvalMapleStatement from c dll.

expression always has form like "F(0.4, 0.7, 0.9);" i.e. maple defined function called. All i need it's value without any kind of caching. But memory usage dramatically grows. Help to overcome it!


Tried already EvalMapleStatement ("forget(F);") - do not work. I'm out of ideas what maple also caches. F itself is complicated enought. And not known a priori. How to clear all caches of other functions that f might call?

How to make maple to change ln(exp(x)) = x?  for example exp(ln(x)) = x, or ln(exp(x+1)) = x+1

How can I most succinctly and straightforwardly get Maple to simplify f below to g below?

> f:=(6*x^2-6*x+6)^(1/2)*(2*x^2-2*x+2)^(1/2);

                          (1/2)                 (1/2)
          /   2          \      /   2          \     
          \6 x  - 6 x + 6/      \2 x  - 2 x + 2/     

> g:=simplify(f) assuming x::real;

                        (1/2) / 2        \
                     2 3      \x  - x + 1/

I want to plot a random ... no, sorry, normal distribution of points around a line.  Let's supose we use the line sin(x) from x=0..2*Pi as an example. 

I have a complex nonlinear long term, I have not found a way to simulate this expression,how I can apply the method of least squares


I want to evaluate an approximation of the solution of the equation eq1 in [0,1] using 4 digits.

In first try, when I first write Digits:=4,  this seems avoid the command fsolve to display the solution.

In second try, when I write evalf(fsolve(eq1,beta=0..1),4),  evalf seems avoid the command fsolve to display the solution.

In the final try, when I write  
> fsolve(eq1,beta=0..1):
> evalf(%,4);
I have...

when i use u and t in the lower bound of summation, everything works fine, as you can see, proc(2,10) gives me a number.



now, if i change u to T[3] and t to T[2], suddenly we have a problem! What gives?

I've finally tracked down a problem I was having to a behavior in Maple I find, possibly, understandable, but need to figure out how to prevent.   Specifically, in expressions of the form x^y, where both x and y may sometimes be zero, the behavior I require is for Maple to evaluate y first so x^0=1 whatever the value of x is.   (Maple does evaulate 0^0=1 itself, I note.)

An example where this sort of thing comes up is in an expression like


Sequencing sequences doesn't appear to work with round brackets

seq( (seq(i,i=1..10) , seq(j,j=9..2,-1)) ,k=1..4)


Hello, I have a problem, when I define some constants like a:=5, b:=6 and than I do some calculation like a+b maple shows immidiately the solution. Is there any way how to make maple to show the numbers at first and then the solution? What I mean is if I define the same constants a:=5, b:=6, then make the calculation a+b. The output i want would be 5+6=11. Is it possible to make maple show the solution this way? I use it for more complex calculation in civil...

We have MapleTA installed on our own server and would like to edit the Login page so that students realize they are on OUR MapleTA page ... students are not particularly observant (no, really!) and often try to login at any MapleTA site they find on the internet.  There is nothing in the UserGuide on editing either the Login or Class pages.



I am working on my project related to bioinformatics. I am using Maple 11 for calculations related to matrices.

I need to calculate  Moore-penrose Pseudoinverse. I need to know the algorithm used by Maple function

'MatrixInverse' for calculating pseudo inverse of matrix.
