Hi all,

I've just started learning Maple. I can't figure it out how to transform my problem into maple syntax.

My problem includes solving a simple algebraic equation, that is,

Y[k+1] = -10*Y[k]

I would like to solve this equation for different values of k, for example, k = 0,1,2,3.

and express my results in terms of Y[0], i.e,.

Y[1] = -10*Y[0];

Y[2] = -10*Y[1] = 100*Y[0]

Y[3] = -1000*Y[0]

I don't know...

hi guys , i want to solve a system of equations but maple gives me "warning, solutions may have been lost" !

what can i do ?

thanks

How to find the integral

1/(4*Pi)*int((cos(t)-sin(s)-cos(t)*sin(s))/(3+2*(cos(t) - sin(s) - cos(t)*sin(s)))^(3/2),[t=0..2*Pi,s=0..2*Pi])?

Its geometric interpretation suggests the answer is -1. Maple finds the inner integrals both over t and s, but Maple cannot directly find the iterated integrals.

1/x!*subs(z=0,Diff(g(z)^x, x$(x-1))) = n*x

1/x!*subs(z=0,Diff(g(z)^x, z$(x-1))) = n*x

how to solve for g(z) ?

as i do not know what do this respect to which variable from a book. so i capture this diagram.

hope that can solve it

L := Summation(Summation(g(m, n)-g(m-1, n)-g(m, n-1), m = 1 .. 3), n = 1 .. 3);

M1 := subs(m=1, g(m, n)-g(m-1, n)-g(m, n-1))=0;

rsolve(rhs(M1),g,'genfunc'(1,b));

Error, invalid input: rsolve uses a 2nd argument, Fcns, which is missing

Reference:

Matrix([[0, g(0,1), g(0,2)],[g(1,0), g(1,1), 0],[g(2,0), 0, g(2,2)]]);

Hi all,

I am looking for a package to calculate the power mean (or Hölder mean) defined like

Mean_p(x_n)=(1/N Sum(x_n^p,n=1..N))^(1/p)

in a hopefully obvious notation. I can obviously implement this definition directly in Maple, but there are subtleties (like the limit of p=0) which maybe a mature implementation already covers (?).

I am still mostly on Maple 15 which does not have such a Mean. If 16 or 17 have it I would not becessarily know.

Hey Forums!

Im using maple 16 for some rather simple Engineering calculatioins. One thing about using maple bothers me, and that is the way my result is displayed.

Here is an example

This piece of code returns a vector 'Sinrdensity' with identity entries. what's wrong with it?

restart;
sinrvalue := [seq(10^((1/10)*i), i = -15 .. 25, .5)];

Sinrdensity := Matrix(1, nops(sinrvalue), 0);

task := proc (sinrdensity, initialpoint, endpoint)

local bft, Theta, bound, value;

for value from initialpoint to endpoint do

bft := unapply(1/(1+I*t), t);

Who knows what Maple does wrong on this one?

Does any one know how to derive this model in Maple?

I did two polar plots as you see and wanted to color the region between them.

> with(plots);
> a1 := polarplot(1, t = 0 .. 6*Pi*(1/3), thickness = 2, filled = true, color = black);
> a2 := polarplot(2*cos(t), t = 0 .. 6*Pi*(1/3), thickness = 2);
> a3 := polarplot(2*cos(t), t = -(1/3)*Pi .. (1/3)*Pi, filled = true, thickness = 2);
> display(a1, a2, a3);

The program makes the region colored red but there is an overlapping part which...

Can you help me how to program about the interference of wave on the water surface in Maple ?

Hi, 

I've bought NAG C Library for my mac in order to use it in Maple.

However, it seems that Maple doesn't know where to search for it.
Indeed, it returns

Error, (in NAG:-h03abc) external linking: error loading external library libnagc_nag.dylib: dlopen(libnagc_nag.dylib, 129): image not found 

I've installed NAG C Library in usr/Library

Thank you very much for your help

Hi there,

I would like to introduce my self and ask you for an advice. 

I have a four linked robot that i would really like to control by the meaning of the optimal control theory. The arm has 4 actuators (giving torques U) in corrispondence of 4 rotational joints. P parameters describe the system.

I got ht edynamic system with the Lagrangian method and now I have 4 2nd order...
