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 :-)

I cannot find a way to create a Gaussian fit to a histogram in Maple12. For creating the histogram I am using the following: > Loading Statistics > Loading plottools > Loading plots

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:

Good Afternoon Everybody,

Attached is copy of Maple file that I'm working on. My first question is, I have used Maple to do linear interpolation inside the procedure to output the coefficient of A(x,T) and B(x,T) with no results would anybody please help.

My second question is if  the variable is a list of values along the length of pile x := [0.0, 2.0, 4.0, 10.0, 15.0, 20.0, 25.0, 30.0]*ft , how should I modify the procedure such that the each value in the list generate A(x,T) and B(x,T).

Please Help.

Regards,

Moses

How can I save an array plot as an eps(or any other format) in maple. Right now when i am trying to do so it saves just one element, (using plot->export->encapsulated postscript etc...). How can I save the complete array as a single eps file.

If I have a univariate in negative powers , say,  a*x^(-1) + b*x^(-2), maple will expand this expression as

a/x+b/x^2

how can I prevent maple from converting negative powers to explicit division in 1D / 2D - Output, i.e. I want to keep the polynomial displayed as

a*x^(-1) + b*x^(-2)

?

 

 

 

 

Dear all, Is it possible for maple to do image cropping? The problem goes like this: i have two images. Image A: a image containing a random shape which is enclosed. Image B: is a normal image What i want to do is: Crop Image B using the shape in Image A. which comes to my mind is: Step 1: read a list of pixels representing the shape in IMAGE A. Step 2: set the pixels in IMAGE B which are not equal to the list of pixels to be "transparent" Is it achievable in Maple? Or matlab can do it also? Thanks all.

which command terminates the execution of the rest of a maple program?

In earlier versions of maple, to jump some characters forward we used tab, but in maple 13 it does sth different, is there any hot key to do that?

Hi,

 

    I am trying to plot a rather complicated funtion in semilog plot. The x axis is in log scale, and x is from 1e-7 up to 10. I was able to have it work out except the points are not uniformly distributed. Most of the points are condensed within a small range between 0.1 and 10. So it is not clear how the curve is like from 1e-7 to 1e-2. Is ther anyway aroung that? Thanks a lot.
