MaplePrimes Questions

Hey all,

Just started using maple for one of my university courses and am having some problems trying to implicity differentiate a question in one of the problem sheets I have to do.

I am trying to find y' for cos(exp(xy)) = x and the command:

implicitdiff(x = cos(e^xy), y, x)

results in a FAIL. Am I doing something wrong?

Thanks!

Hi,

I'd like to verify the Routh-Hurwitz criteria for a 5th degree polynomial. For the last condition, maple computed the quantity. However when I want to expand (with the commands expand or simplify) this expression (in order to check it sign), maple can no longer display it. In fact Maple calculated the expression but cannot display because when I put a colon in front a the expression, it's okay. So I'm looking a way to display those this result. By the way it's a expression with 43302 terms.

Hi all,

I have this small code as example:

> restart:with(LinearAlgebra):
> e1:=5*x1-x2+6*x3+10*x4-10;

                 e1 := 5 x1 - x2 + 6 x3 + 10 x4 - 10

> e2:=x1-x2+x3-10*x4;

                      e2 := x1 - x2 + x3 - 10 x4

> e3:=2*x1+3*x2-8*x3-x4+20;

Hi,

 

I need to know how I can obtain a curve with different color. I work with Maple 15

I have a function like this:

Plot (C1, C2, C3, t=1..200, color= red, green, dark)

where C1, C2, C3 are mathematic function and t is the time because these function depend of time.

I need to know where the curve is obtained how can I know that the color green correspond to the second function?

 

Thanks you in advances.

Hi, I am creating a garden with plan view   in Maple. Garden with plan view

 

I want to create a train in my garden, so i need to create 1/4 annulus. How do I make that?

 

The instructions say:

"To create the X package you have to execute 'maple -s -q X.mpl'
on the command line and then you will get two files X.lib and X.ind."
For some reason I was not able to create the files on the command line (Windows).
Threfore I tried read "C:/.../X.mpl". Now I got the error:
"Error, on line 38, syntax error, cannot open $include file: series.mpl: $include "series.mpl"
Is it the `$´ character to which Maple points to (^...

 I am conveting ordinary differntial equations into polynomial using differential tranformed method and also after using pade arroximants for finding converge point at infinity. because differential transform cannot satisfy boundary at infinity. EQ1 and EQ2 does not built up fromt he preceeding iterations. its pade approximants diagonal value results like pade[3,3],[4,4],[5,5] and so on. i can solve this type for single equations but when  i solve coupled equations...

Hi, 

How can I create a rectangle in Maple knowing 4 points?

> with(geometry);
> point(A, 0, 0); point(B, 0, -15);
print(`output redirected...`); # input placeholder
B
> line(facade, [A, B]);
print(`output redirected...`); # input placeholder
facade
> point(C, -3, 0); point(d, -3, -15);
print(`output redirected...`); # input placeholder
d
> line(facadepar, [C, d]);
print(`output redirected...`); # input placeholder

I have a very simple (possibly stupid) question. 

I am wondering if there is a simple way to model a mass on a rope (or string) in MapleSim, and measure the tension in the rope. Any suggestions would be helpful. 

Thanks,

I have a HOMEUSE licence including Maple 15, MapleSim 5, with Driveline and Tyre Libraries. Does anyone know when the intergated Maple 16 / MapleSim 6 will be release for upgrade?

Hello all,

I'm trying to solve nine non-linear equations for various input. I am using a for loop to vary the input, and for few input combinations there is no solution. I am trying to exclude these and print the values only if there is a solution. After looking at some of the forms I used if (not type(sol[7], numeric) then print("no solution") else print(sol[7]) end if but this is the output I am getting for all the input.

Attached is the maple...


restart; with(plots); with(LinearAlgebra); with(linalg)

Dear All,

I am trying to import data from one maple sheet to another but don't know how can I do that.  Its basically plots which I have to compare.  There is answer to question but as I am begginer I couldn't understand the sharing of engine theory. 

Any simple example will be of great help.

Many Thanks

Hello, 

I am trying to analyse a nonlinear ode. To see the behaviour,

I am using implicit plot (suggested by @Preben Alsholm).

The problem is that every time I need to search for the value of N

(=infinity) to have some sort of graph (needed for analysis).

The other thing is, if we have an output of the implicitplot, How we can be sure

that it is the correct one?
