Hello everyone,

I have been trying to use MAPLE 16 for Boolean algebra computations. BooleanSimplify( ) command in Logic-Mathematics is giving me incorrect results, in the following code:

with(Logic):

f:=(not(x1)and not(x2) and not(x3)) or (x1 and x2 and x4);   #Create a 4 variable function f

g:=((x1 and x2) or (x2 and x3)) or (x3 and x4);    #Create another 4 variable function g

f2:=f &or g;

f3:=Canonicalize(f2,{x1,x2,x3,x4},form=DNF...

I have a set which is represented as a list L (in particular in L there are no repeated values!).

I would like to determine for which index j the element op(j,L) realizes the minimum of L. Is there a built-in function to accomplish this task?

More generally, call OL the list L rearranged in increasing order;  is there a way to determine the permutation which transforms the list L in the list OL?

Hi:

For many reasons, until recently, I have been always using Classic interface under Maple through Maple 16. When trying Maple 16 with Java interface I have noticed several quirks which were not present under the Classic interface of earlier versions through (at least) Maple 13. One of them is this:

The shortcut keys such as CTRL+Insert and SHIFT+Insert do not work and I am forced to use a mouse and copy/paste icons in Maple. This really slows down my keyboard...

hi;
Using Maple 16. In Document mode. Tools->OutputDisplay->2D Math

I want when the output comes out, to be LEFT justified and Not Centered.

The reason is that when I export to Latex, it comes out as

      \[\displaystyle \,{.....

And I do not want the result to be centered. 

I want the math just to be that each equation in the output to start from the 
left edge of the page. So that if I have 3 equations in the output, in my 
latex document, I want them to look like

xxxx
xxxxxxxxx
xx

and not like this

          xxxx
       xxxxxxxxxxx
           xx

I do not mind if it is centered inside Maple itself, on the screen. I just do not
want it to be centered like the above in Latex export. Otherwise
I have to edit the Latex by hand each time I export the Maple document
to Latex and remove the \[displaystyle Latex code by hand. not good.

I looked at the export options also for Latex, and do not see anything
there. I think if I tell it not to show 2D display as displayed equations this should fix things.

I tried 2D Math notation and also Typeset Notation. They both behave the same.

Any ideas?

Hi

I want to solve the equation of

F'''(x)+F(x)*F''(x)=0

with the following  boundary conditions

F(-5)=F'(-5)=0

F'(5)=0.14

for solving it numerically in the computational domain of [-5...5]. I have seprated the domain into two parts and the governing equation and boundary condition in each domain is assumed as follows

g'''(x)+g(x)*g''(x)=0
g(0)=alpha
g(-5)=0
g'(-5)=0

The triangle ABC with A(4,7,5),  B(3,7,-2),  C(0,2,2) is a equilateral triangle. How do i find coordinates vertices of a equilateral triangle which their coodinates are integer numbers? Please help me. Thank you very much.

Here is my code:

restart:

Hi, I'm trying to do this sum in a loop but it says "Error, too many levels of recursion". May I know how should I write it please? Thanks.

for m from 1 to 5 do
Aplus:=Aplus+(m*2):
end do:

I'm trying to get Aplus=(1+(1*2))+(2+(2*2)+....+(5+(5*2))

In geom3d, i have equation a plane. Now i want to get two points A and B in the plane P and write the equation of the line which passing two point A, B. 

restart:
with(geom3d):
plane(P, 2*x + 2*y -z + 4=0,[x,y,z]):

f := (a,b,c) -> eval(lhs(Equation(P)), [x=a,y=b,z=c]): 

T:=f(-1,2, a):
eq:=solve(T=0,a): coordinates(point(A,-1,2,eq)):

We have 1^2 + 2^2 +2^2 = 3^2; 2^2 + 3^2 + 6^2 = 7^2; 2^2 + 10^2 +11^2 = 15^2. Please write for me a command solve the equation a^2 + b^2 + c^2 = d^2, where, a, b, c, d are integer numbers, and d <=100. Thank you very much.

Hi, whenever I write something like A[m](i,j):=0, the clarify expression box will pop out. It will ask me to select a meaning for the expression.

All the expressions in my worksheet is "remember table assignment". Instead of pressing it so many times, is there a way to set it to the particular worksheet so that it will remember the answer everytime I run the worksheet?

Please advice. Thanks.

Dear everyone,

  Hello,

  I have a question about how to get the power 'n' in an expression "(x+y)^n". For instance, I have a Maple code

******

eq1:=4*x^n*y^m+(x+y)^n+x^3;

f1:=map(t -> `if`(match(t = c*y^d, y, 's'), subs(s,d), NULL),
      convert(eq1, list));
f2:=map(t -> `if`(match(t = c*x^d, x, 's'), subs(s,d), NULL),
      convert(eq1, list));

It will be possible to manipulate this behavior with options "dsolve / event" or "dsolve / Error Control"?

Hi Guys,

I was wondering if there is a way to get data from an array solution.

The system of odes, I am trying to solve is 

eq2:= diff(f(eta),`$`(eta,3))+f(eta)*diff(f(eta),`$`(eta,2))+beta*(1-diff(f(eta),eta)^2) = 0;

eq2 := diff(theta(eta),`$`(eta,2))+pr(f(eta)+(beta-1)*

eta*diff(f(eta),eta))*diff(theta(eta),eta) = 0;

bcs:=f(0)=gama,D(f)(0)=lambda,D(f)(N)=1,theta(0)=0,theta(N)=1:

gama:=2;lambda:=1:pr:=10:N:=10:beta:=3:
