Hi, could someone please help with this problem that i'm facing please?

This is that I have :

b2:=zeta->[-y(zeta)      -x(zeta)]^%T

N0:=zeta->[(1-zeta)     (zeta)]

Basically, the first one a 1x2 matrix, second one a 2x1 matrix. I'm trying to do a dot product on it expecting a scalar answer.

I need to find : B2:=zeta->be(zeta).N0(zeta)

It takes like 5 minutes before this statement comes out : "error, ...

Let A(1, -1, 3) is a point; (P): x + y + 5z = 0 be a plane; (l): x= 2t, y = -5t, z = 6t be a line. Write the equation of a line Delta parallel to the plane (P) and has a distance to (l) equal to 1.

I was thinking about this problem many times but i can not 

How can we design a wind turbine and simulate it?

Problem. Let A(-1,5) and B(-2, -2) be two points and l: 3*x - 4*y -27 = 0. Write the equation of the circle passing through points A, B and tangent to the line l.

This is my code.

Restart: with(geometry):

point(A,-1,5):

point(B,-2,-2):

point(C,5,-3):

circle(ABC,[A,B,C],[x,y]):

sort(Equation(ABC)):

tangentpc(l, ABC,C):

sort(Equation(l)):

point(T,a,b):sys:=solve([distance(T,A) = distance(T,B), distance(T,A)=distance(T,l)],[a,b]):

Hello, with "logplot", if I use "scale" or change the minimum vertical range to some smaller values, the plot mechanism will automatically print "0., 0.5*0.0001, 0.0001, 0.5*0.001, 0.001, .... " at the y-axis numeric mark.

However, I want the 10^(-n) numeric format and alwasy keep the format.

How could I always get the 10^(-n) numeric format for y-axis ?

Thanks a lot!

Hi all,

A while ago, I had asked a question relating to calling to an MapleSim .msim simulation within maple .mw worksheet. (Thank you Acer! :) I got it working but then another issue just popped up...The basic structure is as follows:

********************************************************************

A := MapleSim:-LinkModel('filename' = "TriplePendulum_WORKS_v2.msim")

for z from 1 to 50 do

     initialize_variables;

How can i specify the ground field C= complex numbers and calculate a primary decomposition for an ideal defined over C? For example

with(PolynomialIdeals):
J:= <x^2 +1 >;
PrimaryDecomposition(J);

should return x+I, x-I, but instead returns x^2+1

Hi,

how can i install the DirectSearch optimization package for mac version (MAPLE 15)?

Dear all,
Some time ago I asked a question on maple primes concerning handling the numeric solutions of dsolve procedure.

They sent me to the discussion on option remember and indeed this helped a lot.
However there is another issue.

The method I am trying to implement requires iterative calls to dsolve/numeric with one of the functions defined from the previous...

Hi everyone,

My question is as following:

Given the numeric solution to the dsolve call as a procedure, I define a function of this procedure, say

u(x(t),t), where x(t)=proc(t)..proc - output from dsolve/numeric

Is there a way to have u as a function of t only and not of procedure x(t) and t?

Thanks in advance for any help

Hello

I need a procedure to unjumble a series of 9 letters into discernable 4 to 9 letter words. each letter can only be used once and it needs to include a given letter in each word. eg IOCMRELAE, and include R in each word

Acer did a similar thing a while back, but in this case it needs to tell it to permute 9 letters, then 8,....,then 4 (each including letter R).

Hi, can you please show me how to use the Hankel function on Maple please?

Here is my equation, "P²a(P)_,PP+Pa(P)_,P- Ra(P)+P²a(P)=0" i'm trying to solve for "a(P)". Subscript of P means partial differentiation.  

Many thanks

Hi, this is probably very simple but I can't seem to get Maple to show me the Matrix that I want. Could you please let me know what is the problem?

N₀:=s->1-s;

N₁:=s->s;

N:=s->[N₀(s) N₁(s)];

Both `$`N(s) and N(s) shows me the statement "error, in N[0] too many levels of recursion"

Then I change to N_j:=s->[N₀(s) N₁(s)];

The solution comes out to be [N
