Seems that I don't know how to organize a nested loop.

Simple example:

for i by 2 to 19 do

for k from 2 to 26 do

A := i*k

end do

end do

Nothing is returned here (when I expected a list of different values for A).

Hi everybody,

I want to plot a function f(x,y). I know I can do this with plot3d(f(x,y),x=-1..1,y=-1..1) and this works. But now I want to do something else: x and y fulfill g(x,y)=0 and I want to create a new function h(x) that is basically the old function f(x,y) except that for each x he has to take the y so that g(x,y)=0. Then I can do plot(h(x),x=-1..1). 

OK, this is easy if g(x,y)=0 can be solved for y. But life ain't simple ;-) and in my example this is impossible. I hope anybody has an idea?

I have a parameter r which is between a and R, a less then r, r less then R - real or complex numbers, whatever, I need to integrate following function:

1/4*Pi*int(dr1/|r-r1|*int(dr2/|r-r2|*int(dr3/|r-r3|,r3=a..R),r2=a..R),r1=a..R);

The problem is that Maple always says, that it's unable to determine if r is between a and R, how can I assign r into this interval?

I create equations with so many terms.

And MAPLE print out me NOT all of terms of equation.

for example,              ...........  +`[...10000 terms...]`+..............

But, I want to See these terms!!!!

How can I SEE these terms??

Thank you for reading my Quastion!

Hello, in the attached graph I have scheduled some inequalities, but it shows error, you would know what is that?

Hello, anyone knows why the next page graphics not anything in the server, Maple works,

but seeing it from the link does not display anything,

what should be?

I'm missing a command to generate Bell Polynomials in Maple. Only Bell numbers can be computed. Or are they somehow tightly related so that a separate command would be overkill ?

Hi

I am trying to solve a pde equation with matlab , but i cant, please guide me:

eq_u_0 := diff(u[0](x,t),`$`(x,4))+a*u[0](x,t)+diff(u[0](x,t),`$`(t,2))=0;

bc_u0 := u(0,t) = 0, u(pi,t) = 0, diff(u[0](x,t),`$`(x,2))(0,t) = 0, diff(u[0](x,t),`$`(x,2))(pi,t) = 0, u[0](x,0) = a*sin(x), diff(u[0](x,t),t)(x,0) = 0;

pdsolve(eq_u_0,{bc_u0});

with convert and FormalPowerSeries one can find power series of some functions. WIth the function int one can sum / make integrals of expressions.

I am new to Maple and have tried finding the sum function of the product of two power series :

in both cases sum of n from 0 to infinity
 
how to program Maple to find the sum function of f(x), g(x)
and g(x)*(f(x) ?

a:=[ [ 6,3],[5,6],[6,6],[5,8],[4,7],[5.5,10],[6,12],[5,11],[5,13]]

how do I select the list sets, say that contain in the first position 6.  Something like

if a[i][1]=6 then put the pair in a list.

Hi everyone.

For example, I have

...

plo[i] := plot([u[i](t), v[i](t), t = k[i] .. k[i+1]])

...

Now I want to draw all these plots on the same picture:

with(plots):display([plo[1],plo[2],plo[3],..........................................]);

How can I place all plots in brackets? Number of iterations varies, and there are a lot of sets of iterations, so I need a universal way to do it.

Tried to use Array() but didn't suceed.

Thanks for help!

Hi,

I try to plot the deflection of a skyscraper. Therefore I need a very long calculation and the constants c_1 to c_14.

Dear fellow forum members,

I have decided to write a simple package for Maple. No decent package is complete without documentation.

Dear All,

Is it possible to make Maple assume all variables in a worksheet are real, instead of having to apply to the 'assume' command to each variable indiviadually? Thanks!

Can someone point me in the right direction?  I want to simplify equations of the type:  4*2^n into 2^(n+2).

Thanks!
