i have a problem when i input this code in maple,..

how it can be error?

what the solve?

thanks for help me

the code:


> with(plots); with(DEtools); with(plottools); a := 0, 5; b := 0, 2; c := 0, 7; d := 0, 2; E := 0, 1;
                                    0, 5

Dear Readers,

Given an expression for e.g. x^n+ y^3.5, how to extract the symbolic/floating point exponent, I tried with degree method but it fails whenvever there is symbolic or floating point exponent. Is there any alternative ?

 

Thanks,

In the folders Maple 16: there is a file named MapleToolbox_Window.exe. What can I do with it?

hi 

if I have two partition Pi and Pi 'I want to know the decomposition of Pi' 

I want to solve numerically the nonlinear problem 

a*(diff(y(x), x, x))+2*(diff(y(x), x))+exp(y(x)) = 0, y(0) = 0, y(1) = 0

by defining my own method defined as 

yn+1=yn+2*h*(-2*yn+2*ln(2/(1+x))-(1/2)*a)^2/(a*(-4*yn+4*ln(2/(1+x))-a-h*(4*yn-4*ln(2/(1+x))+a+x+1)/a))

where h is the step-size. Please help me by letting me know how can I do this using Maple 11.

 

how can I caculate the Clifford Algebra in using symbolic expression?

Hi,

   The error showed up whenever I tried to do the Maximum Likelihood Estimation with Global Optimization Toolbox.My objective (likelihood ) function f is defined as follows(A1 to A5 are intermediate variables; parameters  are x[1] to x[12]):

   f := 0;

   for j from 1 by 1 to 21 do

       A1 := exp(x[1]+x[2]*c[j]);

       A2 := exp(x[3]+x[4]*c[j]);

Solve the equation (x-2)(25-x^2)=1

Let function f(x)=x(2011+√(2013-x2)).Find maximum and minimum value of function f(x)?

Is there programs or algorithm to obtain resultant of multivariant polynomials for more than 2 polynomials

Please help me to check this procedure for solving complex DAE, I want to plot this error figures

There are some errors for the initial conditions?

restart;
with(plots);
w := 10;
L :=0.001;
R :=1;
u(t) :=exp(I*w*t) + 2* exp(I * 2 * w * t);
daesys:={diff(I3(t),t) = 1/L*u(t), I1(t) = I3(t) + 1/R * u(t), I1(0)=0, I3(0)=0};
dsys1:= map(eq -> (evalc(Re(eq)), evalc(Im(eq))), eval(daesys, {x(t) = xre(t) + I*xim(t), y(t) = yre(t) + I*yim(t)}));

Hi everyone,

I am importing an .m file from MATLAB to Maple using the command: FromMFile(). The .m file uses a set of huge symbolic matrices with an output of a huge symbolic vector of 36 by 1. Each element of this vecot is supposed to form a second-order differential /or algebraic equation that I am planning to solve using the Maple DAE toolbox.

The problem I have is that while I execute the worksheet, Maple only evaluates the...

How does one go about defining a road surface that can be used with the tire library for doing road holding on hills and side slopes?

I need to use Krylov functions widely in my project. They are recurrent functions as follows:

Can I make Maple operate with these functions?

Thanks.
