hi, what code do I use to sum the number of heads from a random coin toss to illustrate the Central limit theorem (relationship between the binomial and normal distribution). The more approachable the code is the better..

I'm very confuse with this question:

- Find one root/zero of  2*x^5-5*x^4+3*x^3-3*x^2+x+2 using Newton's Method. If your polynomial is sadly lackaing in a root, subtract some constant value until the polynomial cuts the x-axis

- Produce four iterations of the Newton's Method. This will result in four successively accurateapproximations to one solution of p(x)=0

- For each iteration, report your beginning x_n and the subsequent x_n+1 value. For each run, also product a graph of p(x) and the graph of the newest Newton created tangent line

solve({x11*x11+x12*y11+x13*z11=x11*x11+x12*x21+x13*x31,

x11*x12+x12*y12+x13*z12=x11*x12+x12*x22+x13*x32,

x11*x13+x12*y13+x13*z13=x11*x13+x12*x23+x13*x33,

 

x11*x21+x12*y21+x13*z21=x21*x11+x22*x21+x23*x31,

x11*x22+x12*y22+x13*z22=x21*x12+x22*x22+x23*x32,

x11*x23+x12*y23+x13*z23=x21*x13+x22*x23+x23*x33,

 

x11*x31+x12*y31+x13*z31=x31*x11+x32*x21+x33*x31,

Hi,

I have a matrix with 3 columns and I want to change the order of columns 2 and 3. In fact  column to must be column 3 and vice versa. I was wondering if there is a function that I can use? (the number of rows is variable)

Thanks,

Ibo

I use Optimization package and I obtain a warning

"Warning, no iterations performed as initial point satisfies first-order conditions"

What is the first-order condition?

Thanks,    Sandor

 

I was playing with a problem from the Maple NG, one can state it as
  
  Int( arccos(x) / ( 1+x^4) , x=0 .. 1)

Maple 11.02 gives a result, which numerical can not be valid.

Using real (!) partial fractions (Maple uses decomposition over the
complex, no?) I got a similar problem with denominator = parabola
(and continuity over the integration interval):

  Int( arccos(x) / (x^2 - x * 2^(1/2) + 1), x = 0 .. 1)

Some more and time-consuming consuming experiments reduces troubles
to the following example, where symbolics are disproven by numerics:

Hi,

First of all, I am wondering if this is even possible or even generally used... Maybe what I'm trying to do is not defined or whatever... I dunno.. But I'm gonna ask anyway.


What I want is to make a polar plot, with a different range.

I have a function r(a) which obviously calculates some radial distance as a function of the angle a.

I have so far found 2 ways to plot this in a polar graph:
with(plots):
plot(r(a), a=0..Pi, coords=polar)

hi, if generate 10 random 0 and 1's by using the following maple code > restart: > coin:=rand(0..1): > coin_1:=proc(n) seq(coin(),i=1..n) end: > data1:=coin_1(10); How can I count the number of sequences that have a lenght equal to 1 zero, 2 zero, 3 zero, 1 one, 2 one, 3 one etc etc and how can I plot it in a histogram to illustrate the law of large numbers alex

When I use maple in the shell of Linux, I  always get this kind of output of polynomials:

  2       2        
a  - 2 y  + b y.

My question is could I get them in more regular form,

a ^2 - 2 *y^2  + b* y.

Any idea?

 

Hello,

I've problem to make the plot to animate [plot]. Please help. Thanks. Below are the commands

As many of you have experienced, the maplet MathMLEditor, has some problem when it comes to interpret correctly the typing functions, even some functions with the help of the palette.

I was trying to input this function : sin(4*x)+cos(2*x) but after moving form the unknown tag _XML_ error, I end up with misinterpretations of this function, to things like  4*sin(x)+cos(2*x).

So, the comments in this blog tells that the better solution is to use a TextField to get the input function, but now I face this problem

f := Get('txtFunction');
 

Is there any command or Maple package for computing subresultant sequences of two polynomials? It is hard to believe that Maple doesn't include this basic facility but I can't find it anywhere.

Thanks,

Peter

Why lhs cannot be resolved? Well, it can be, in fact, if the interval is t=0..0.03, say, but I need to use t=0..infinity, or t=0..smthbigenough. Thanks.

fsolve(1-erfc((1/2)*sqrt(2)*sqrt(t)) = 0.5e-1, t, t = 0 .. infinity) = fsolve(1-erfc((1/2)*sqrt(2)*sqrt(t)) = 0.5e-1)
