I have defined a function G, which has only one input parameter. I'm excuting following code.

sum(G(13-j), j = 0 .. 2)

with debug swiching on for 'sum' and 'G'. I got following error message:

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

{--> enter G, args = `+`(13, `-`(j))

I have a fairly easy question but I am new to Maple and can't seem to figure it out w/ Maple help or anyone online resources.  The problem is list all pairs of integers between 100 and 110 that are relatively prime.  (I think) I can make it work by doing:

for k from 100 by 1 to 110 do gcd(k, 100), gcd(k, 101) . . . ; end do

but what if the problem had said pairs of integers from 100 to 1000? I don't understand how to iterate this function for more than one variable.  Any help would be appreciated.

I just noticed that Maple 13 does not accept aling option of center whereas Maple 9.5 does. Is there any other option that I can align the texts in center?

 

I want to import about 1400 data entries from an excel 2008 spreadsheet into a vector form in Maple12. I saved the excel data in .txt format, and used ImportData command to import some of the data in Maple12 spreadsheet. This approach works for a limited number of data entries because the maximum number of rows in Maple12 spreadsheet is 100, so I cant use it for a larger number data entries. To my knowledge, ImportData stores info as an rtable-Vector or Matrix. I also know that some information is stored in placeholders. How can I access the information stored in placeholders?

Hi,

I have a set of equations which I need to solve.  I have them in LaTex format (can anyone tell me how to post them here in a better format?) they are:

(\partial_t - i x) \textbf{b} = -\frac{3}{2 \bar{\omega}_A} b_x \hat{y} + i \textbf{u}

(\partial_t - i x) \textbf{u} = \frac{2}{\bar{\omega}_A} u_y \hat{x} - \frac{1}{2 \bar{\omega}_A} u_x \hat{y} - \frac{3}{2 \bar{\omega}_A} \partial_x Q \hat{x} - i Q \hat{y} - i \frac{1}{\kappa} Q \hat{z} + i \textbf{b}

\frac{3}{2} \partial_x u_x + i \bar{\omega}_A u_y + \frac{i \bar{\omega}_A}{\kappa} u_z = 0

Hi all!

I'm new in Maple, and i need help on this: I need to create a Hypermatrix (3D) and i don't know how.

Please help me, because I need this to begin a project on my University.

Thanks for any help.

the assignment: Sketch the region in the plane consisting of points whose polar coordinates satisfy the given conditions. 2<><>

 

Hi, I work with DifferentialGeometry package. How can I convert a differential form into a list? For instance: dx^dy+dy^dz-2dz^dx ---> [dx^dy,dy^dz,-2dz^dx] Usual convert (that works this way with polynomials) does not work here. Is there any way to get over this problem? Alexey

Hi!

 

I am given a set of data (ie - x= 0.1, 0.2, 0.3 .. 1.5; y= 21.2, 19.7, 13.5; examples, not what I actually have), and I need to perform a sine regression on the scatter plot I get derive from this data. Up to this point, I have used maple to plot a scatter plot, and then I've had to use my TI-84 to get the equation for the best-fitting line. I don't want to have to enter all these data twice, and I just know that maple is capable of doing this. Can someone please help me figure this out? If you need it, I can give you the real data set I'm using at home.

How to get an trig equation like sin(x)=1/2 or cos(4x)=sin(x) on the form x=a+2pi*n/b n= 1, 2, 3... in maple 12.

More details and examples in the attached file.

Thanks for your help :-)

Hi all,

since i found a way to replace a function like sin i was wondering about it's behavior. I replaced it with:

sin := proc(x):-sin(x*Pi/180);end proc:

The main problem is when i use the proc it execute like a normal proc, and not like the actual sin function. here is some exsamples:
