Is there a way that I can plot this in Maple?

The question is:

Shade the region of the complex plane for which  (I*z-1)/(z-I)  is real.

This is real when x² + y² = 1 and (x,y) ≠ (0,1). How can I plot both of these things on one plot in Maple?

Codewords:=proc(L,x,y,z)
local
List:=[];

if L=S then
if x=1 then

print(`A 1 j k`);
else
print(`A 0 j k`);
fi:


if y=1 then

print(`B i 1 k`);
else

print(`B i 0 k`);
fi:
if z=1 then
print(`C i j 1`);
else

print(`C i j 0`);
fi:
fi:
if L=A then
if x=1 then

print(`S 1 j k`);
else

print(`S 0 j k`);
fi:

if y=1 then

print(`C i 1 k`);
else

print(`C i 0 k`);

How can I sort a list with radicals?

a:=[sqrt(8),sqrt(2),sqrt(39),-sqrt(5),sqrt(26)]

sort(a) returns the same list in the same order. 

Hi to you all, I'm brand new to this forum and I hope you could help me.

I wrote a Maple14 worksheet which perform data analysis, reading information from a set of file (usually 50 files) coming from an acquisition device. They are text file but the acquisition software produce them in the form:

namefile-0Ep.irr, namefile-1Ep.irr .... namefile-49Ep.irr

where "namefile" is the name I choose when i start the acquisition.

In order to perform...

I solve system of ordinary differential equations numerically by method=rkf45 (Runge-Kutta Fehlberg method).

1. Maple 13 installed on the Linux x64. Processor – AMD Phenom (4 cores). When Maple computes it uses only one core but other three cores stand idle. How to impel to compute other cores?
2. When I solve system of ODE a calculation reaches closely 1 ns and stops. Maple writes that value of Maxfun exceeded. But I need solve system up to 10 μs....

Hello

I am trieng to solve an equation which has two solutions. but maple cant tell all of them at once. I have to change the range.

los := fsolve(2.062648062*10^(-8)*sqrt(8.607207774*10^11*x+2.976566118*10^18-5.312602135*10^9*x*ln(x))-0.1721820163e-1*sqrt(x)-30. = 0, x = 10^5 .. 10^9)

gives me

los := 1.296433174*10^5

and

los := fsolve(2.062648062*10^(-8)*sqrt(8.607207774*10^11*x+2.976566118*10^18-5.312602135*10^9*x*ln(x))-0.1721820163e-1*sqrt(x...

Hi! I've tried to figure out what to do with plot([sin^2(x),line(x)],x=-2*pi..2*pi,y=-.1..1.1,tickmarks=[spacing(pi),default});

Warning, unable to evaluate 1 of the 2 functions to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct.

original problem is f(x)=sin^2(x). I had to plot with the tangent line.

I played aorund a bit with the "Insert Table" command and it seems to create just an inert object that cannot be accessed or operated upon except directly by typing into its boxes. Is that true? Is it just for word processing?

Is there also a possibility to fill the region (area) between for example the curves x^2 and x^3? I can not find it and I am afraid it is not possible.

Hello

i want to solve this equation

but i couldn't

please help me

( x mod 5656 = 565 ; x mod 565 = 56)

Why the command

does not return eps???

How can I simplify expressions like this?

I am new to this, so should be simple.

i define a function p

> p := proc (x) options operator, arrow; 10*x-20*piecewise(x < 2, 0, 2 <= x, x-2) end proc;

Hi,

I've got a pretty intensive run going on in Maple and I wanted to speed it up. It involves computing every power up to some large number (100,000+) of small matrices (2x2) but with very complicated abstract polynomials inside. There's really no way to speed this up as far as coding is concerned so my only option is to use multithreading, since I need mutiple runs, or run this on some faster server/cloud.

1) Multithreading will...

sendtomap1.mw, sendtomap2.mw, wood_riess.zipHi! I've written a program for my work to obtain "chi square" for a range of data. Can someone tell me why my first example which I have attached and I've called it "sendtomap1" works correctly, but the second one "sendtomap2" has an error?...

why won't VectorCalculus[Jacobian] accept vectors?

... to prevent me from frying my system? or is it an unnecessary restriction?

Here's what I mean:

Fvec := Vector([x[1]*x[2],3*x[3]]);
Xvec := Vector([x[1],x[2]]);
Flst := [x[1]*x[2],3*x[3]];
Xlst := [x[1],x[2]];
VectorCalculus[Jacobian](Fvec,Xlst);
VectorCalculus[Jacobian](Flst,Xlst);
VectorCalculus[Jacobian](Flst,Xvec);

Error, invalid input: too many and/or wrong type...
