Take a look at the GRTensorII home page here. All versions of Maple are covered. There are additional papers and more tensor related links as well. Regards, Georgios Kokovidis Dräger Medical

You can do it numerically. Take a look at the help pages below for examples. >?erf >?stats[statevalf] Regards, Georgios Kokovidis Dräger Medical

An example below. The "display" command allows you to view multiple functions on the same plot. ?display for more help. >with(plots): >f1:=plot(3*x^2,x=-4..4): >f2:=plot(-3*x^2+40,x=-4..4,color=blue): >display(f1,f2); Regards, Georgios Kokovidis Dräger Medical

Like this? >y := sum(a[k]*sin(k*Pi*x/l), k = 1 .. 3); y := a[1]*sin(Pi*x/l)+a[2]*sin(2*Pi*x/l)+a[3]*sin(3*Pi*x/l) sum - definite and indefinite symbolic summation Sum - inert form of sum ?sum or ?Sum for more help on this Regards, Georgios Kokovidis Dräger Medical

Try this and see if it works for you. V2 := rhs(op(B3[2])); Regards, Georgios Kokovidis Dräger Medical

>restart: >with(geom3d): >plane(p1,2*x+y-z=1,[x,y,z]): >plane(p2,2*x+y-z=6,[x,y,z]): >distance(p1,p2); Type ?geom3d for more help and examples regarding geometric problems. Regards, Georgios Kokovidis Dräger Medical

Right click on the plot. Select Axes and then Properties... Click on Vertical Axis and see if the options there will do what you want. Regards, Georgios Kokovidis Dräger Medical

I tried your statements below with Maple 10 and 11 Classic interface. I never lost connection to the kernel. I also removed the restart commands to see if that made a difference. It did not. I just got an error message, as expected. >restart: >A := Array(symmetric,1..4,1..4): >B := Array(ArrayIndFns(A),A): >ArrayIndFns(A),ArrayIndFns(B),evalb(A = B); symmetric, symmetric, false >restart: >A := Array(symmetric,1..4,1..4): >B := Array(ArrayIndFcs(A),A): >ArrayIndFns(A),ArrayIndFns(B),evalb(A = B); Error, argument `Array(symmetric,1..4, 1..4, [[...],[...],[...],[...]], datatype = anything, storage = triangular[upper])` is incorrect or out of order Error, invalid input: ArrayIndFns expects its 1st argument, A, to be of type Array, but received B Regards, Georgios Kokovidis

When I click on forums, it takes me to this thread right away. This is not right. Regards, Georgios Kokovidis Dräger Medical

Maple 10 classic interface. Should work with the other one as well. >plot((x*(11-2*x)*(8.5-2*x)),x); You can cut and paste the above line into your worksheet to see if it gives you the right result. Regards, Georgios Kokovidis Dräger Medical

For data files like the one above, the readdata command works very well, and it can handle floats as well. ?readdata for more help on this. Regards, Georgios Kokovidis Dräger Medical

Take a look at the Conference paper presented at the 2002 Maple Summer Workshop here. Regards, Georgios Kokovidis Dräger Medical

I need some clarification on your question. If your list contains n/13 and n=1..5, then what kind of remainders are you looking for? There are none. You can construct your list with n=1..5 with n/13 as follows: >restart: >[seq(n/13, n=1..5 )]; The square brackets around the seq command return the answer in list form. For remainders of integer fractions, look at the help file for the irem command. >?irem If I missed something, or this is not what you are looking for, repost the exact problem with your expected outcome. Regards, Georgios Kokovidis Dräger Medical

What version of Maple are you using? The maximize function is available in version 10 and 11. So is the numerical version Maximize. Both commands were used in the posting by Robert Israel. The Global Optimization Toolbox is an add on product that has to be purchased ($1,695.00). It requires Maple 11.
