polygon_2_color.mw

Imitation coloring both sides of the polygon in 3d.  We  build a new polygon in parallel with our polygon on a very short distance t. (We need any three points on the polygon plane, do not lie on a straight line.) This place in the program is highlighted in blue.

Paint the polygons are in different colors.

Hello,

I am new to Maple. I am working on PDE and I wanted to try an easy example to know how to work with Maple. So, I startted with the example from the HELP, but still get error as shown below. Can someone guides me.

Thank you.

How can I make tick marks on the 2-D plot more visible. Attached is a figure created using my maple 2015 student edition

Eight matrices inside the list J:

J := [Matrix([[1, 0], [0, 1]]), Matrix([[0, -I], [-I, 0]]), Matrix([[0, -1], [1, 0]]), Matrix([[-I, 0], [0, I]]), Matrix([[-1, 0], [0, -1]]), Matrix([[0, I], [I, 0]]), Matrix([[0, 1], [-1, 0]]), Matrix([[I, 0], [0, -I]])];

Function member identifies J[2] as a member of J and returns its position in j:

member(J[2], J, 'j'); j;

Matrix multiplication inside a loop does not have a matrix type:

for i to 1 do for j to 2 do a := J[i].J[j]; member(a, J, 'k'); print(i, j, k, a, whattype(a)) end do end do;

Has anyone any ideia of what is going on?

Hi every one, I'm trying to plot the function f which is functions in terms of Bessel functions:Here is the code plz any advise i'll be grateful.

Hi,

So I'm trying to generate a .dat file that has x in the first column, then the output for y1 in the next and y2 in the following, where y1 and y2 are functions of x so the data file would look something like this from x=-5..5 in equal steps of 0.01.

-5          12           8
-4.99     7             5

etc

I'm struggling to get my head around how to do this, i understand i should use the seq function in maple and save it in array of sorts and then use writedata, but im not sure how to piece it together for having 3 columns

thanks in advance for any help!

Valery Ochkov and Volodymyr Voloshchuk have developed a series of thermal engineering applications in Maple 2016. The applications explore steam turbine power generation and refrigeration cycles, and use the ThermophysicalData package for fluid properties.

Their work can be found at the following locations on the Application Center.

• Valery Ochkov
• Volodymyr Voloshchuk

I especially like

• this application, which optimizes the extraction pressures of a steam turbine to maximize its efficiency,
• and this application, which plots the state of a two-stage refrigeration cycle on a pressure-enthalpy chart.

Hi, may I know how I should write the commands after I convert my 'Hello' to 34 and 27 by using the commands below..

Hope someone can help me, thanks a lot..=]] Have a nice day~

message:=’Hello’;

>Hello

plaintext:=convert(message,bytes);

>[72, 101, 108, 108, 111]

P:=numtheory[cfrac](plaintext);

M1:=numer(P);

>9418838187

M2:=denom(P);

>130799212

with(Bits):

bitM1:=Split(M1);

Think I've solved my problems, thanks.

Hello

I have a complex equation EQ, it gives me 4 answers - two complex, one negative and one positive. Which assumptions do i need to use to automatically get one answer - real and positive one?

I tried similary to what I did with real equations:
simplify(solve(EQ)) assuming real, positive
But that didn't work

How do i make output (that blue part i get after pressing Enter) go in one line? Sometimes it's easier to look at one line of answer (even if it is longer than all other parts of the documents) than to look through row after row of equations.

And also - is there a way to hide output? There are many not important equations and i want to see only a few plots and a result. How do i hide outputs - because when i just delete them - maple deletes associated variables.

objectiveproc := proc(mmm)
...
return Trace(abs(M));
end proc:
with(Optimization):
i := 0:
t := 1:
Minimize(objectiveproc(x)-abs(Trace(abs(MA))));

Error, (in objectiveproc) invalid subscript selector

This procedure calculate the equations of motions for Euclidean space and Minkowski space  with help of the Jacobian matrix.
