i write the followinf code in maple

eq1:= f'''(x) - f'(x)

is this posible in maple that i worte the above command like this

Linear:= d3/d(x) - d/d(x)

eq1:= linear (f)

thanks for youe attention in advance


i have 2 equation named eq1 and eq2 with 2 unknown parameter a and b which each equation dependent to a and b. i want to achieve critical a and b to minimize eq1 and eq2.

previously i have eq1 and one parameter a only and i use the NLPSOLVE command. but , for above mention problem i dont know how achieve a and b?


thancks for your attenrion in advance

Hello everyone !


First of all, excuse my English if it's difficult to read, I'm french.


I'd like to draw a surface/shape in 3D in spherical and I used plot3d with coords=spherical to do so. But I'd like to color on the picture to change when R(theta,phi) changes. I could visualize how R is changing and where it is the same. But I have no idea how to do so...


I can't put the picture here, the formula is too long...


> assume(y::prime)

> about(y);
Originally y, renamed y~:
  is assumed to be: prime

I don't understand this answer:

> is(sqrt(y)>0)


how can I solve memory used limitation problem on MAC OSX LION .After memory indicated on the bowwtom of the sheet reaches 57M it freezes.

Dear Maple Users

I have been testing Maple 16 for some time now, and I am overall very pleased with it. There is however one issue, which is really annoying. In previous version of Maple, images inserted into Maple and plots were printed much bigger than they looked like in the Worksheet. Then me and other users have requested to have the printed output look more like it does in the Worksheet on the computerscreen. Maple has adressed those user complaints in the new...

Not really a review but I think Maple has so much cool stuff one can do with it, that we get sidetracked from one project to the next.   Before you know it, a new release is out and you've put your project on hold to try out and play with the new features - and not really forging ahead on any projects.  One year between new releases isn't enough time to have customers really, and I mean really, dive into Maple.

Here is what a reviewer at computing world said about Maple16

Hi friends
This is strange for me, but Maple could not solve the below integral. I tried with online version
of Mathematica and it solved for me. The solution is Hypergeometry function. 
> f := ((1/2)*r+1/r)^(1/n);

> int(f, r);
What is the problem?

This does not make any sense to me :-)

A := Matrix([[seq(i, i = 1 .. 10)], [seq(i, i = 11 .. 20)], [seq(i, i = 21 .. 30)]]):
A[.. -1,..] ;
A[.. -2,..] ;

You would assume that A[..-1,..] would remove the last row but that is not the case!
Instead you have to do A[..-2,..] he he it seems a bit odd!


Is there any syntax highlighting for the "code edit region"?



I need to solve some  transcendental equations, using Maple 16 which i need to transform or bind with java later. My problem is I cant evaluate.

Equation I would like to evaluate is  k= ln((M-m)/m(k-1))offcourse I  defined m and M, prior to c.
Both  eval(k) and evalf (k)  only return k,  I need value for further calculations.

I'm very new to Maple and I'm just curious as to how Maple computes its summations with the MatrixPower command.

if A = a real square matrix

c = some real constant

x = c*A

then Why is it, that when I try to use...

sum(MatrixPower(x,k), k = 0..3);

I get a non-real / ridiculous result, but when I type it out...

MatrixPower(x,0) + MatrixPower(x,1) + MatrixPower(x,2) + MatrixPower(x,3);

x^0 + x^1 + x^2 + x^3;

Dear Maple Users

In Maple 16 I read in the menu Help > What's New that it is now possible to have 3D plots exported as vector graphics, when using EPS export. I tried it, but could not open the resulting EPS file. I used my CorelDRAW 15 Suite ... Can someone tell me how I get access to the exported vector graphics?

If I cannot get it into CorelDRAW, it is not for much use. Maybe an intermediate process?




I'm currently having some issues while trying to find a way of getting the CPU usage inside Maple.

Is there any existing Maple function that will return the percetage of the CPU usage ?

I have Zipped 2 equations together to equate their equivalent Coefficients.  I now need to assign solve the list fot each value of N (1...9) How do I get Maple to do this reliably for the list as N 1..9 does not necessarily occour in sequence.
