Dear Sir / Madam,
Could you recommend me how to find the square root of the complex equation correctly?
My equation looks like this
sqrt(complex_equation_1^2 + complex_equation_2^2).

Hi,

I am trying to expand the following into a polynomial on maple:

to get  1 + x + 2 x^(2)+ 3 x^(3)+ 5 x^(4)+ 7 x^(5)+ 11 x^(6)+ 15 x^(7)+ 22 x^(8)+ 30 x^(9)+ 42 x^(10)...  

I tried to use the expand() code...

Consider the expression below.

r:=1/2 * exp(I*k*theta - 1/2*k^2*sigma^2)* sigma*sqrt(2*Pi) + 1/2 * exp(-I*k*theta - 1/2*k^2*sigma^2)* sigma*sqrt(2*Pi);       -------(1)

BY HAND I can factor out the sigma square root of 2 pi and one of the exponents to give.

sigma * sqrt(2*Pi...

Hi everybody:

I am having problems with the expression shown below.

X[1](s) = (s^2+2)*s/(1+s^4+3*s^2);

Specifically, when I try to find the inverse of the Laplace transform I get

x[1](t) = (1/10)*(sum((_alpha^2+4)*exp(_alpha*t), _alpha = RootOf(1+_Z^4+3*_Z^2)));

which obviously is not what I am looking for. Realizing that the problem must be the denominator I try to factor it using the factor command. That does not work either. If I do the factoring myself, that is

Can be developed in Maple, the figures mentioned in the following article: The Fundamental Theorem of Linear Algebra?

Im quite new to Maple, how do I extract the imaginary part of sqrt(I)? Im sure it is just Im(sqrt(I)) and Re(sqrt(I)), but the Im part just returns the real part againg for some reason, does anyone know what I am doing wrong here?

I'm using maple 9 by the way

>sqrt(I);

Hello,

I have the following problem:

I have an array of values stored in F[i,j] and plot them using the LineChart tool:

LineChart([seq([seq(F[i, j], j = dmin .. dmax)], i = 1 .. 3)], xcoords = [seq(0.1e-1*2^(k-1), k = dmin .. dmax)],  color = mycolor);

This way, I obtain 3 curves, each of them with a different color as defined by mycolor.

However, for a publication in black and white I would now like to assign different linestyles...

Hey you maple experts

I have been trying to change the font in maple. In my try i suddenly dont get no output document mode.

Can someone please help me?

I have to answer the following question:

simulate a modified simple random walk starting at 0 which at each step, in addition to possible unit jumps to the right (with probability p) and to the left (with prob q), may stay at its current position with probability r>0, so that p+q+r=1. We have been given the hint to type in

if (u<p) then x:=1 else if (u<p+q) then x:=-1 else x:=0 fi; fi;

and to rename the procedure, but i have no idea how to carry out the simulation?

Quick question, why doesn't the following return a~?

> define(g, g(a::realcons) = a);
> assume(a::realcons);
> g(a);
                              g(a~)

How do I get it to do so?

Thanks!

I work on large matrices but I only need the eigenvector associated to the largest eigenvalue. How can I do that?

Many thanks.

How to explain, in Maple, Ax as a combination of the columns of A?

dy/dx=(y²-1)/(x²-1),  y(2)=2

Hi there,

            Basically i performed some calculations on maple and obtained a set A with about 8000 integer outcomes.

Im trying to create a loop that counts how many times there is an outcome of the integer 70 out of the 8000.

So far I have created the following:

A:=[10,20,..........]

s:=0

if A=70 then do s=s+1 end;

But this is not working

Any help will be appreciated

If I enter the code below the end result is outputted as  Pi/Pi (pi over pi). But I want an output of 1 not pi over pi. How do I get maple to return 1 ?

test:=int((1/(2*pi) + cos(k*phi)), phi=-Pi..Pi);
t1:=value(test);
