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

HI experts,

can anyone here help mi in transform a Mathematica v8.0 sheet into maple v.15 ?

I am still maple novice.

Thanks a lot

Let A(-5,-3,-3), B(0,1,-2) be two points and

(d): x = t - 3, y = 2*t, z = t+2.

Find the coordinates the point M on (d) so that the area of the triangle ABM obtain minimum value.

This is my code.

restart; with(LinearAlgebra):

A:=: B:=: M:=:

u:=A-B: v:=A-M:

T:=CrossProduct(u,v):

S:=minimize(1/2*Norm(T,2), location = 'true');

M:=subs(op(1,op(1, S[2])),M);

Let A(-2, -1, 3), B(0, 1, 4) be two point and

(d): x = -t-2, y = t+1, z = -t-1 be a line.

Find coordinates point M lies on (d) so that area of the triangle ABM equal to 3*sqrt(5).

This is my code

restart; with(LinearAlgebra):

A:=: B:=: M:=:

u:=A-B: v:=A-M:

T:=CrossProduct(u,v):

sol:=solve(1/2*Norm(T,2)=3*sqrt(5),{t});

for i from 1 to 2 do print('M'[i]=(subs(op(sol[i]), M[1]), subs(op(sol[i]), M[2]),subs(op(sol[i]), M[3]))) end do;

i have a function f(alpha)=1+2cos5alpha, i had no trouble plotting f(alpha), but when i try to plot f(alpha.t) i keep getting empty plot.

please help

create the function f(x)=(x²,x=<0), (2x, 0<x<1), (2sin(Pi.x/2),x>=1). how do you find derivative in one command and integrate f(s)ds from -1 to 2.

Hello,

I have created a MapleSim model including a few custom components. When I try to run the simulation, I receive the following error:

cannot resolve function `Main.'Typesetting:-mambiguous'`; there is no function `'Typesetting:-mambiguous'` visible in model `Main`

How do I know where the source of the error is?

Thank you,

Behzad

how do you analytically and numerically solve the IVP: y" + 4y' + 13y = cos2t, y(0)=2, y'(0)=-1.

Let A(1,0,0) be a point and two lines

d1: (x-5)/3 = (y-1)/1 = (z - 2)/2,

d2: (x-5)/1 = (y-1)/1 = (z - 3)/3

Let B and C be two point lies on d1 and d2, respectively so that the three points A, B, C

If log₁₀5 =c and log₂₀50=d express log₉40 in terms of c and d ?
