Hello, I'm trying to find a function f(r,r') such that G(r,r')=1/(r-r')+f(r,r'), where r=sqrt((x-x')^2+(y-y')^2+(z-z')^2). I have 6 boundary conditions of the form: G(x,y,a)=0, G(x,y,-a),=0, G(b,y,z)=0, G(-b,y,z)=0, G(x,c,z)=0, G(x,d,z)=0 where a,b,c,d are known constants. How do I do that in maple? Thanks

i need to find real roots for (a*x^3 + x^2  - a*x + 1) as a function of a.

and i need only the REAL roots to show in the output, no imaginaries.

thanks

Hello, I am completly new to Maple and basically any kind of programing at all. I have a project for my Calc 3 class that consists of 5 problems. And I have absolutley no idea how to get any of them done. I have been sitting in the computer lab at school for almost 4 hours and have made very little progress. Anyways, I was wondering if anyone could help with a coulple of these questions to get me going.

 

If i am writing the following code in Maple 11 it gives me the postscript picture with a black frame around.

Why the option noborder is not working?

myPlot1:= plot(sin(x), x= 0..10, axes= boxed, color= black, scaling= constrained, view= [0..10, -5..5]):
plotsetup(
  ps,
  plotoptions= `noborder,width=5cm,height=5cm`,
  plotoutput= "myPlot1.eps"
);
plots[display](myPlot1);
plotsetup(default)

i've read one RNG source code from an article and some of the code are not clear to me. The source code is

proc()

local t;

global seed;

      seed:=irem(a*seed,p);

      t:=seed;

      to concats do seed:=irem(a*seed,p) t:=s*t+seed; end do;

end proc();

 

Hi,

 

I am trying to size a postscript plot in Maple 12.

I don't seem to have any control over the plot size with the width, height, axiswidth, axisheight options.

Is there something I should be doing to get control?

 

Additionally, is there a way to tie these values into the plot export facility?

 

Regards

 

Hi there, I have some .txt files with a large ammount of measuring Data, which i would want to draw in a XY-Graph. It is structured as follows: 1 15.0000 1.120000E+02 2 15.0003 1.460000E+02 3 15.0006 1.140000E+02 4 15.0008 1.340000E+02 5 15.0011 6.600000E+01 6 15.0014 1.100000E+02 7 15.0017 1.370000E+02 8 15.0019 6.000000E+01 9 15.0022 9.200000E+01 10 15.0025 5.200000E+01 and so on, till:

end

 

 

 

 

 

 

 

'pv:=p2'); %The variable a is matlab variable 'm:=m');'m1:=m1');'f:=piecewise(x>=pv[i], 1/(m1), x<pv[i], 0)')maple('r:=sum(f,i=1..m1)');

 

 

What did I do wrong, or why does Maple 11's cumulative distribution function (cdf) for Statistics:-GammaDistribution differ from what theory suggests? http://www.mapleprimes.com/files/7371_GAMMA_CDF.mw Thanks heaps.

Good Day,

Please assist with helping me in figuring out how to input math problems into Maple12. I am enrolled in MA 141 and my deadline to finish the course is June 1st. This class is very confusing and I would really appreciate if someone can assist me. thanks in advance.

One of my problems are: Find the absolute value of the complex number: z=9-5i

I have no idea how to input that into the software to get the answer...

Hi there,

I need to differentiate a summation like

sum(sum(u[i,j]^2*d[i,j]^2,j = 1 .. N),i = 1 .. c)

in relation to an arbitrary element, say u[s,t].

I usually get 0, whereas the expected response is

2*u[s,t]*d[s,t]^2.

Does anyone know if this is possible in Maple?

Thanks,

Antônio.

 

Hi there! I am discovering the Physics:-Vectors Package a bit, and as an example i wanted to calculae the Tensor of moments of inertia I, for a continuous mass disribution. Maple Help contains an Example-Worksheet on the Physics:-Vectors Package, that also contains calculating some Inertia-Tensor I, but for a discrete mass distribution. The formular there is entered as follows: > restart; with(Physics, KroneckerDelta): with(Physics:-Vectors): Setup(mathematicalnotation = true);

program a procedure repeatedEls which takes a list and returns the sublist consisting of all elements that appeared more than once in the given list.

repeatedEls([a,b,c,d,c,d,e,f,a]);

[a,b,c]

i need to write a procedure for two sets whose final output is their intersection.

 

help!
