Hello,

I tried implementing anti-commuting variables in my program with the use of physics package:

 Physics[setup](anticommutativeprefix=theta);

Checked that theta is anticommuting:

type(theta_i,anticommutative);

Received true, however computation like:

theta_2 * theta_1 - theta_1 * theta_2 ;

Gives 0, not accounting the anticommuation properly. How can i fix this?

Find the principal arguments of the 5 roots of the polynomial:p(z)=z^5-5*z^4-5*z-5,and enter a decimal approximation to the largest principal argument in the box below.  Your approximation should be correct to 10 significant figures

Can some one tell me how to write in maple？correct answer is 2.691121659

Find, to 10 significant figures, the unique turning point x0 of f(x)=3sin(x^4/4)-sin(x^4/2)in the interval [1,2] and enter it in the box below.x0=？

How to write this in maple？

I need to test a list of numbers to find if any of them are complex. if a complex is found then remove that complete row from the list. the potential complex numbers in my list are a, b and c. b is complex i.e has a non zero imaginery part in row 1 so only row 1 should get deleted. the a b and c were originally generated from the arcsin function. Would appreciate help on this. I know it should be simple enough to do. Thanks in advance.

I'm using the 64-bit version of Maple 16.0 and Excel 2010 (32-bit). (Most people using Office 2010 install the 32-bit version on 64-bit operating systems.)

Is it possible to use the Maple addin with the above setup ? I tried selecting WMIMPLEX64.xla, but Excel appears to want WMIMPLEX.xla (from the 32-bit).

What is the easiest fix ? Can I find a copy of WMIMPLEX.xla and use with with Maple64bit and Excel32bit ? Do I need to uninstall Maple64-bit and install Maple32-bit ?

Hello to everyone

Pls help,urgent....

I need to draw the deformation of one story building (for simplicity, 4 columns and 2 floors) whose columns and floors  under influence of external load acting to the left of the building at its intersection point undergo the deform shape like S . So means that when the building moves to the right its intersection point of column and floor has some small rotation.

I am new to Maple environment...

Suppose a Record is created as follows in Maple.

> r := Record( foo = [ ... ], bar = Record( ... ), ... );

If this is saved with save() command to a text file, a new line is automatically inserted at every fixed character length, and it is very hard to read. I want the Record to be stored to a text file in more human readable way. Is there any good way to do that easily?

I have a column vector of lists. FWIW, it was generated by numerically solving an ODE and then map-ping the solution over a vector with values for the independent variable, like "yt:=map(solnn,xv)" where xv is a column vector with floats and solnn is the result of a dsolve(...,numeric). Each element of the solution vector yt has the form [t=..., y(t)=..., d/dt(y(t))=...] and has the type List.

I want to extract the solutions for y(t) (i.e. the numbers only) into a new...

i am modeling a simple standing wave. i have created three plots y1, y2 and y and then i am using animate to move them. the problem is that i cant add a legend describing every plot and i am not getting how to do this.

in addition when i click on the plot and then go to the legend menu, both show legend and edit legend are disabled.

here is my code

with(plots): y1:=0.01*sin(Pi/2*x-40*Pi*t);

                 y1 := -0.01 sin(-1/2 Pi x + 40 Pi t)

I'm very new to maple and i want to use DEplot to plot phase portraits.  how do i do this? I am using maple classic.

Hi, I am trying to put a for loop inside another for loop, but it is not working. but if i split it up, it works, may I know what is it i miss out please?

eta is a diagonal matrix.

I tried writting

for i from 1 to 17 do
nod:=(2*(i-1))+1;
diz:=eta(i,i)
end do

for j from 2 to 18 do
nod:=(2*(i-1))+1;
diz2:=eta(j,j)
end do

but when i try to combine it

for i from 1 to 17 do
for j from 2 to 18 do

When maple does gauss elimination for matrice(student linalg). In "edit matrice" can i solve for x1,x2,x3..?

Hi, How do I check what sort of matrix is it by asking the right question?

For example, M is a 3x4Matrix

I type in "whattype(M)", it gives me the answer "matrix".

May I know what I should type so that it shows me that it is a "3x4 Matrix" please?

Thanks

Hi there,

I am trying to find an analytical solution to an integral. Unfortunately, I only get the function call returned. Is there anything I can do to get Maple to solve it?

Thank you
