I have the fractcal of a snowflake

Problem. In the plane 2*x -3*y +3*z -17 = 0, find a point M such that the sum of its distances from the poits A(3, -4, 7) and B(-5, -14, 17) will have the least value.

First way.

restart:with(geom3d):

point(A,3,-4,7):

point(B,-5,-14,17):

plane(P,2*x - 3*y +3*z -17=0,[x,y,z]):

reflection(Q,A,P):

line(BQ,[B,Q]):

Doc3.docx  

suppose my matrix is in the form as i attached in Doc3.docx

how should i find the determinant for that M1 matrix in the attached document programatically,

i fint the determinant of M matrix programatically, but how to find it for M1,M2 ........M6.

please help me with solution.

Thanks and Regards,

ppdev.

Hello,

I always used something different from D when using diagonal matrices. Now I learned I can unprotect D.

However, I got this:

> restart; with(LinearAlgebra);
> unprotect(D);
> D := DiagonalMatrix([2, 3]);
> D.D;D^(2);
Error, invalid 'D' operator

Maple does interpret D as a matrix that he can square, but the exponentional notation can't be used as he sees it as some sort of operator?  Can anyone point out my mistake?

Use Newton’s Method to approximate the indicated root of the equation to correct six decimal places.

The root of 2.2x⁵ – 4.4x³ + 1.3x²-0.9x-4.0=0 in the interval [-2, -1].

The rest of the assignment states : "

Start by plotting the function in
Maple to get a reasonably good initial approximation. You may use a
“while” loop, but do not use existing Maple commands for Newton’s

Hey Guys,

I'm new to Maple and am having problems two problems. The first is I can not get anything to show up on my plot and the second is I'm getting a erorr of "Error, (in fsolve) Can't handle expressions with typed procedures". The code can be seen below;

When using Maple 15, sometimes the pagackages and formulas that were previously defined seem to completely drop it.  I'll load packages and assign variables at the beginning of my project, yet after maybe 10 minutes or so, I have to redefine my variables and reload my pacakges.  I have noticed that it happens more often if I try to switch over to the "Text" tab and then back to "Math."  It's very intermittent, Maple will be working just fine churning out graphs,...

Hello.

if I write N[0]:=1; and press enter, I will get the response

N[0] := 1

Now if in my large document I happen to have defined a variable b:=5; then later 

I try to define another variable N[b]:=1; and press enter, I get this response:

N[5] := 2

But N[b] has nothing to do with "b". Why does Maple do this? Is there 

some concept I am missing? In what context is this useful?

many thanks.

helo to all i want to know how to solve a lp model having 4 decision variables and 4 constraints means how to solve them to get  optimal solution . Plz guide me ,thanks  : )

eq1 := x+y+z+a*t-s = 0;
eq2 := x-y+2*z-t = 1;
eq3 := 2*x-y+t+s = a;
eq4 := 2*x-3*y+z-2*t+2*s = 3;
eq5 := -y+4*z-3*t-s = 0;

solve({eq1, eq2, eq3, eq4, eq5}, {x, y, z, t, s});

I need to solve this system in any case in which the value of a is not 2. If I substitute a by 2, the system is solved, but if I try to solve it like this or if I try to substitute a by any value that is not 2, not even an error appears.

What the hell am I doing wrong? I've...

HI,

I measured some points. This points are plotted in a graph. Now I want to make a fit on this points.

I now that the fit-function has to be like this:

F = A + B1 x e^(-t/C1) + B2 x e^(-t/C2)

Problem: how can I create a fitting function like that?

The best thing I found is the "spline"-fit, but it doesn't work properly. It has to be one lonely function, not a summary of several functions (like spline).

I have a problem with solving these two equations.

When I put this into maple -> solve([0.4=a*cos(b*8)+3 and 0.2=-a*sin(b*8)*b],[a,b])

It say: "Warning, solutions may have been lost". I don't know what to do.

why do i get this 

"Error, (in solve) cannot solve expressions with diff(diff(y(x), x), x) for x"

when i input these: 

> restart; with(DEtools); with(plots); with(linalg);
> ode2 := x^2*(diff(y(x), `$`(x, 2)))+x*(diff(y(x), x))+4*y(x) = -2*x+7; bc2 := y(1) = 7, y(4) = -1;

a := 1; b := 4

ic2 := bc2[1], (D(y))(a) = alpha

constraint := lhs(bc2[2])-rhs(bc2[2]); constraint = 0

Hello,

I have a big problem With maple, it's a bit complicated, but I will try to detail. it's been months since I still looking for the solution :

I have a profit function expressed as follows:

Hi,

I am trying to implement some numerical algorithm for an optimal control problem (still).

It involves double cycle. In the inner one two DE systems are solved sequentially and the result is used to update values of some objective function.

This part uses remeber option thanks to pagan  and is ok.

However, in the outer cycle I use the values of this objective function to obtain solution for yet another DE and update ICs for the inner cycle.
