Hi,

First of all, I am wondering if this is even possible or even generally used... Maybe what I'm trying to do is not defined or whatever... I dunno.. But I'm gonna ask anyway.


What I want is to make a polar plot, with a different range.

I have a function r(a) which obviously calculates some radial distance as a function of the angle a.

I have so far found 2 ways to plot this in a polar graph:
with(plots):
plot(r(a), a=0..Pi, coords=polar)

hi, if generate 10 random 0 and 1's by using the following maple code > restart: > coin:=rand(0..1): > coin_1:=proc(n) seq(coin(),i=1..n) end: > data1:=coin_1(10); How can I count the number of sequences that have a lenght equal to 1 zero, 2 zero, 3 zero, 1 one, 2 one, 3 one etc etc and how can I plot it in a histogram to illustrate the law of large numbers alex

When I use maple in the shell of Linux, I  always get this kind of output of polynomials:

  2       2        
a  - 2 y  + b y.

My question is could I get them in more regular form,

a ^2 - 2 *y^2  + b* y.

Any idea?

 

Has anyone implemented https for Maple T.A. 3.01? Mainly we are looking to secure the login and password information, but if everything must use ssl, that's ok. Thanks.

Bonjour

Je voudrais savoir s'il était possible de faire fonctionner un maplet sans la visionseuse mapletviewer. Et dans le cas contraire la faire fonctionner à travers un serveur maplenet, Mais je ne sais pas comment m'y prendre. Quel est la démarche à suivre ?


Merci de votre aide.

Hello,

I've problem to make the plot to animate [plot]. Please help. Thanks. Below are the commands

Expand the Dirac delta function in a series of Legendre polynomials using the interval

-1 <= x<= 1.

Can anyone help with number 12.2.5?

 

thanks,

very respectfully,

 

 

 

Is there any command or Maple package for computing subresultant sequences of two polynomials? It is hard to believe that Maple doesn't include this basic facility but I can't find it anywhere.

Thanks,

Peter

Why lhs cannot be resolved? Well, it can be, in fact, if the interval is t=0..0.03, say, but I need to use t=0..infinity, or t=0..smthbigenough. Thanks.

fsolve(1-erfc((1/2)*sqrt(2)*sqrt(t)) = 0.5e-1, t, t = 0 .. infinity) = fsolve(1-erfc((1/2)*sqrt(2)*sqrt(t)) = 0.5e-1)

 

It is very stranger that these two statements are not equative:

evalf(Int(x*sin(x)/(1+(cos(x))^4),x=-Pi/2..Pi/2));

 1.845096351

 evalf(int(x*sin(x)/(1+(cos(x))^4),x=-Pi/2..Pi/2));

 1.323830675+0.*I

I think the first one is correct. In fact, the exact result is

 2*hypergeom([1/4, 1/2, 1, 1], [3/4, 5/4, 5/4], -1);

u can evalf the above answer to check it. In fact, Maple cannot get this analytic answer, how do I get it?

Hello:

      i have a presentation in recent days.  in this presentation i need copy some formula result in maple to Powerponit. But when i copy formula directly, it shows discorder code in Powerpoint.

    so does anyone has good method?

   thanks very much!                             

Solve differential equations using type=series option. How can I judge the series is convergent? Can I obtain the expression of general term?

 

If I try this

 

>

solve({1*x+(1/2)*y+(1/6)*z =1,(1/2)*x+(1/6)*y+(1/24)*z =0,(1/6)*x+(1/24)*y+(1/120)*z =1}, {x,y,z} );

Maple 11 gives me the answer {x=63, y=-384, z=780}

However the book mathematical problem solving with computers (2002) maple 5.3 gives an answer of

{x=39, y=-216, z=420}
