Hi every one,
here is a question about drawing and filling in Latex (\usepackage{tikz})
I just draw a circle with 5 sectors correctly,
and what I need help on please, how I fill 3 sectors with green color
and the other 2 sectors with red...
please help me with this task...
Hello every one, I need help on some mathematica run program.
Suppose the following:
1) 2=<t=<1000
2) r=3+2Sqrt[2]
3) k=(r^t+r^(-t)-20)/4
4) n=2k+4
5) x=n/2-(r^t-r^(-t))/2Sqrt[2]
I need to run the program For[t=2,t=<1000,t++
and only print if it found any...
Count from "MatrixForm" in mathematica!
Hi every one, I really need help on this task..
how do I Count only the zeros elements from a MatrixForm in MATHEMATICA
Suppose I have a Matrix 100X100 full with numbers and
I just need to know how many zero is there on this matrix
thanks
I tried the the first one and the out put was:
My x: 0 my y: 0
I do not know if its checked all the values correctly?
how to make it print for example on each 50x
x=50 no solutions
x=100 no solutions
x=150 no solutions
.

Hello every one, I need help please...
How to write in mathematica to solve an equation of x and y that is equal to 0,
(i.e. y^4+2y^2x^2-15x=0)
and let the program try all the value of x=0,1,2,3,...,10000.
and all the value of y=0,1,2,3,...,100.
The program should start with x=0 and try all...
Hello every one, this question for a mathematics experts...
Suppose we have the matrix
M =
\left| {\begin{array}{cccc}
9 & 6 & 0 & 1 \\
3 & 7 & 2 & 5 \\
1 & 0 & 2 & 8 \\
8 & 8 & 1 & 0 \\
\end{array} } \right|
and we want to print only the coordinates that equal to 0...
Thanks Norwegian..
I think you are right, can you explain in detail please.
you can see that
|a_2|=|a_{m^2-2}|
so if we prove that a_2 = 0, then a_{m^2-2} is also = 0.
what about
a_{\frac{m^2}{2}}
micromass + Mark44
I do not know what the is difficulty of a_i that is facing you both !
Knowing that I told you before a_i is the coefficient of z.
if you still have a problem with a_i, just put m = 3 for example.
you will get
1 + 3 z - 8 z^3 - 6 z^4 + 6 z^5 + 8 z^6 - 3 z^8 - z^9
then you...
OK,, :)
Let
n=m^2 and\,\,\, s=\binom{m}{2}, n-s=\binom{m+1}{2}
prove that the following claim is true
\sum_{i=0}^{n}a_iz^i=(1-z)^{\binom{m}{2}}(1+z)^{\binom{m+1}{2}}
Prove of summation claim ??
Hi every one,,
any idea how to prove the following claim
\sum_{i=0}^{n}a_iz^i=(1-z)^{\binom{m}{2}}(1+z)^{\binom{m+1}{2}}
i think we need to use some derivatives, may be the second derivative will help.
please help.
Find the integer zeros for equation of degree 8 ?
Hi I am trying to find the integer zeros of the equation:
y^8-28y^6x+112y^6+210y^4x^2-1540y^4x-420y^2x^3+2464y^4+4200y^2x^2+105x^4-11872y^2x-1260x^3+8448y^2+4260x^2-5040x=0
I know that I need some substitution to make the degree goes down.
for...
