hi I want to write a program that convert a polygon to triangle, that is if we have polygon with 6 edges, how we can get triangle from it using edges or vertices??

I am biginner,

It is well know that the quintic equation is not solved by radicals generally. Although the solution for quintic equation is expressed explicitly by using Jacobi theta functions, in the following site I tried to find a differential equation as a solution for inverse function of general quintic polynomial, and found it is expressed with the 5-th degree nonlinear differential equation.

Dear all,

Would appreciate some guidance for this question:

If q = ax + by and r = bx - ay, determine the value of:

 

Hi everybody

I am doing this calculation:

I have my maple code as follows. I don't see why I got "Error, invalid subscript selector"? can anybody help me? Thanks in advance!!

>a := [2, 2, 3, 3, 3, 5];

b := [2, 2, 2, 3, 7];

for k to 10 do

  for j to 10 do

       c := b[k]; d := a[j];

if c = d then a := subsop(j = NULL, a);

    print(a);

     print(k);

    print(j);

     break

else print(k);

Hi, all

I tried by:

>alias(a=RoofOf(z^4+z+1)):

> if a > 2 then print('yes') end if;
Error, cannot determine if this expression is true or false: 2 < RootOf(_Z^4+_Z+1)
 

Any ideas?

Thank you.

Hello,

I want to write a programme that convert a polygone into triangle, Can any one help me please.

i am new to maple.

Regards

I created three different matrices which are A,B and C. I tried to calculate 4(AB)C but when I command it,it gives me an error. Does anyone know how can I do that?

I also need to create a system of three different linear equations with unknown that has one solution. My equations are 2x+3y=8 -x+2y=3 and 3x-4y=-5.Can anyone tell me how can I plot these lines, solve the system by using solve command and how can I solve the system using by matrices and row operations?

Hi,

I'm trying to find my way around using pdsolve. The problem I have now is how to handle the result it return me. From the psdolve help page, for example, we have the following equation returned (eq. 1.2) :

f(x, y) = _F1(x^2+y^2)

Dear friends,

I am stuck with this question.

X, Y AND Z are the angles of a triangle and f is a function defined as

f = sin X sin Y sin Z

1) Express f in term of X and Y only
2) Prove that f is a maximum if the triangle is equilateral

Hope someone is able to help me through.
Thank you.

Try this out:
dt:=[2.5, 3.9, 2.9, 2.4, 2.9, .8, 9.1, .8, .7, .6, 7.9, 1.5, 1.8, 1.9, .8, 6.5, 1.6, 5.8, 1.3, 1.2, 2.7];
Statistics[Histogram](dt);

You can see the tickmark for frequency/vertical axis is wrong. The leftmost bin hits somewhere more than 0.8. Option "frequencyscale=relative " does no help. But option "discrete=true" or change some setting about bin, such as bincount ..., can help. It seems a bug? Or my understanding about histogram is not right?

I have multiple XY pairs from multiple sensor data which I would like to display on the same plot.  I can easily do this in MATLAB, but referencing Chapt 5 of the User's Manual indicates ways to plot multiple plots when plotting relations, but nothing I found pertains to actual numeric data sets.  The only plot command I found was "PointPlot" & it appears it can only plot a single data set at a time.

Any suggestions?

When I press shift+enter, I get a new line, but how do I remove the line ? (highlighting it does not always work, so I can't seem to manually delete it)
