I have an iBokk G4 with OS 10.3.9 and i tried to install Maple 10. After the autentification the install procedure simply stops. When i try to install Maple 9 everything goes fine, but when I doubleclick the Maple symbol it jumps a few times and then simply stops again. I always used maple on this computer until i couldn't start maple 9. I also tried to reinstall the whole os system but that doesen't helped either. Does anyone have the same problems or know a solution, that would be a great help since I need maple for my studies. Michael
I know there is an option in fieldplot that is "fieldstrength" in maple 10. However I need to know if there is some sort of equivalent option on maple 9.5's fieldplot, or another idea on how could I do it, because I'm trying to plot a field and my vectors are just too big on the center and too tiny when distance from the center grows. Of course I know that is inherent to the fields that are proportional to inverse square of the distance, but still I wanted that *something* other tiny unrecognizable dots appeared in my vector field... Thanks
I wish to set the default location for the "backup files" so they don't clutter my $HOME directory. It seems to me that this should be an easy thing to do but I can't find any reference in any of the documentation sources. Everytime I use Maple and quit my home directory is littered with as many as 45 small files which (I presume) are intermediate save files from a session. I don't mind having the program autosave but can I assign this location to some special scratch folder? OS: Mac OS 10.4, G5, Maple 10.
Hi; Could somebody please let me know about finding functional derivative of H respect to m where, >restart; >H:=int(u(x)^3+u(x)*diff(u(x),x)^2+2*u(x)^2,x=-infinity..infinity); >m:=u(x)-diff(u(x),x$2); by using Maple? Thanks a lot Sayed
How would I enter in a derivative problem such as f'(3) when f(x)=x^2+8x+4 into maple 10?
I need some help!! I need to show the following using MAPLE 9.5: Suppose I have a symmetric 4 x 4 matrix whose entries are all positive, called A. Suppose also that I have a random vector in R4 whose entries are also all positive, called c. I already have a routine to determine the largest absolute eigenvalue of the 4 x 4 matrix, called L. I need to show that the vector v, calculated as follows: v = lim[(A^n)c / (L^n)] as n tends to infinity is an eigenvector of A, with eigenvalue L. Any suggestions??
How do I take sin of a matrix?
How can I plot a function with an integral domain? For example how would I plot f(n) = 1/n for n=1..10 or g(n)= n! for n=1..10 or h(n) = g(n)-f(n) for n = 1..10? Any help would be appreciated. Tom
I'm trying to write some code that will rewrite an expression of the form R = expr => newExp = 0 Then take all the coeffiecents of newExp with respect to the variables (var) and replace them with new coefficients of the form a.1, a.2 etc and finally put it together with the variables again to obtain the new expression. This is the code i've got so far and it doesn't work, not used to working in maple so can't really figure out the problem... strRpm := proc(expr, var) local num, den, k, maxIndex, zeroform, R; num := numer(exd); den := denom(exd); zeroform = expand(R*den-num);
I want to maximize x*y*z subject to U= (10-x)*(10-y)*(10-z). My Lagrangian function is: L:= x*y*z + lambda* (U - (10-x)*(10-y)*(10-z)); # (I assume that values of x,y,z are between 0 and 10) assume(x>0,x
Does anybody know whether Optimization[Minimize] is the equivalent of matlab's "fminsearch"? If it is, then it will save me from having to move all my project work away from Maple =) Elaine
Hi, When I write the following commands.. I get only one surface in R3.. is not possible to add one option to have more surface levels (automatically)? implicitplot3d(x*y*z, x=0..10,y=0..10,z=0..10); implicitplot3d((10-x)*(10-y)*(10-z)^2,x=0..10,y=0..10,z=0..10); In fact, in contourplot we have one option contours=10 which allow us to draw the 10 contour levels.. Is not possible to do something similar with implicitplot3d?. Thanks in advance for your comments. JJ
Hi, I'm trying to draw a 3D graph of some points that I have generated in Excel, so I need to be able to import the data somehow into Maple then be able to plot it. I can produce the data in two formats, the easiest is a grid with x values along the side and y values along the top, then the z values fill in the grid. Alternatively I can create 3 columns, x, y, and z, so that the number of rows is the number of data points I have. I've been trying this for hours and haven't got very far. I've managed to get the data into Maple (version 10) using the Assistant - Import Data option on the Tools menu, and this produces some kind of matrix of my data. However it won't let me plot it!! Any help would be much appreciated!
Hello, Sorry for my basic english. I try to solve an equation using MAPLE 9.5, and i use the instruction RootOflike this RootOf(-125000000000*sin(1335041/4000000*Pi)*_Z^(7/10)*Pi+95867020225*cos(1335041/4000000*Pi)+3473522985*I*cos(1335041/4000000*Pi)-511700000000*_Z^(7/10)*Pi*cos(1335041/4000000*Pi)-59499404367158*sin(1335041/4000000*Pi)). Maple can not solve this equation.it answers me by re-writing the same thing : RootOf(-125000000000*sin(1335041/4000000*Pi)*_Z^(7/10)*Pi+95867020225*cos(1335041/4000000*Pi)+3473522985*I*cos(1335041/4000000*Pi)-511700000000*_Z^(7/10)*Pi*cos(1335041/4000000*Pi)-59499404367158*sin(1335041/4000000*Pi))
Hi.. Is there a Maple pcocedure to evaluate the arithmetic mean of the n preceeding datas (of a data) in a list of numbers? Thanks
