I want to plot a bunch of straight lines with positive slope in one colour, and I want to plot a single line of negative slope in another colour.

I hope my code is self-explanatory:

restart; with (plots):
myEqns:=NULL:
for i from 1 to 5 do;
 myEqns:=myEqns,y-x=i;
od:
myEqns:=[myEqns];
 [y - x = 1, y - x = 2, y - x = 3, y - x = 4, y - x = 5]
implicitplot([op(myEqns), y+x=0], x=-10..10, y=-10..10, colour=[red,blue]); 

Dear all,

I am a beginner at Maple. A friend of me has told that Maple can solve analytical solutions.

In other words, I want to combine three equations ( a linear system)  in order to conclude to the final solution.

Has Maple the ability to solve analytically a linear system of 2 or more equations? 

Thank you very much in advance.

Kind Regards

I'm trying to have Maple work through ideas involving the Fundamental Theorem of Calculus, and am encountering a problem with the programming of Maple.

I begin by defining a function like:

F(x) := int(x^2,x)  (or equivalently, F:= x -> int(x^2,x)  )

Then I ask Maple to evaluate F(2).  I expect to get 8/3 but instead I get this error message:

Error, (in int) integration range or variable must be specified in the second argument, got 2

even if I use a simple x^2+y^2 plot I get these funny gaps at the botom of the plot. I have looked through the FAQ files and can't seem to find a solution to it... is there one ?? from what I have seen so far there does not seem to be an easy solution. with a graph like the type above to change to coords=spherical or cylindrical does not show the same graph due to that change.

Hi,

I tried to implement an small example sheet for using the RSA algorithmen with small numbers. Unfortunatly, I get confused by my own program and have difficulties to figure out what I am doing wrong. My message can be decoded with both keys, the public and private key what is obviously not correct.

below is my code with some comments:

restart: with (numtheory):
p := 13; # my first prime number
q := 23; # my second one

n := p*q;

I am of interest about using StateSpace(de, invars

Hi all,

How can I plot, say, y1=x+4, 0<x<5 and y2=2x+1, 0<x<10 on the same plot area?

Thank you,

I want to construct a sequence of diffenrential equations with

seq(diff(f[i],x)=k[i]*f[i],i=1..4);

but I get

0 = k[1]*f[1], 0 = k[2]*f[2], 0 = k[3]*f[3], 0 = k[4]*f[4] 

Is there anyone can tell me what I have done wrong? Thanks a ton!! 

This is my situation, please help me.

How to load Maple-NAG connector to execut this example ?

Is it an additional program to install ?

Hello,

I was wondering if someone could assist me with the code for listcontplot.

I've tried the following:

M:=Student[LinearAlgebra]:-RandomMatrix(4,4);

listcontplot(M);

But this does not work.  Is there any way to use listcontplot, listcontplot3d, or any other command to generate something similar to what Excel calls a Surface - contourplot?

Thanks.

I see how to get the solutions of the Schroginger eqn

I have the function r=sqrt(1+(cos(2*theta)) and theta E [0,pi/2] I need to find the arc length of this function using maple 14

so far i have this

with vector (calculus):

ArcLength(sqrt(1+cos(2*theta)), theta=0..pi/2)

I dont know what to do after this

"I" is reserved for square root of -1.  I don't use complex numbers and want to use "I" in my equations.  How do I go about doing this?  I tried to unprotect it with a number of variations of quoting "I".

I'm using document mode with Maple 13 on Apple.

Thanks for your help.

My question is how do i get Maple to simplify every calculation that involves units automatically, right now i have to do this manually for every single one.

For example: This values all come from variables wich have units assigned to them.

Then i hit right click, Units -> Simplify and i get this:
