How do I show the 126 different permutations of tic tac toe?

Hi! We just got the new Maple 14 and I'm having problem creating the resource file by using this command: "Maple14WindowsInstaller.exe -r". My steps are that I want Maple 14 to be the default application, no shortcut on the desktop and we are using a network server for our licenses. But, each time it gets to the installing part and seems to do nothing at all! In fact, once I let the installer run for 2 hours and it didn't installs anything. In other words, I can't create a resource file. I tried to run it on VMware workstation using Windows XP Pro SP3 French Edition, tried to run it on a normal computer running Windows XP Pro SP3 French Edition, etc. without any success. So any help will be greatly appreciated!

Thanks in advance for any help!

 

I have a set of points and 2 questions

Each point has different values associated with them.  I want each value of the points to be displayed as a specific symbolsize.  The only way I could figure out how to do that was to create a list of the points of one value and set it at a specific size, for example like this.

Suppose pointset a has value 1
a:=[[1,2],[3,4],[5,6],[4,4]]

and suppose pointset b has value 2
b:=[[2,2],[3,3],[4,4],[2,3]]

I think the only way to do what I want is this

I'm running OSX and Maple 14. Now when I do ]>? mod for example it (maple) is launching a Maplet (which crashes) in order to do something (perhaps bring up a Java version of the docs?). How do I disable this and get the old (text based) man pages back?

how can i solve two coupled differential equations like these: s1 := diff(n[D](t), t) = a-b*n[D](t)^2-c*n[D](t)-e*n[D](t)*n[T](t); s2 := diff(n[T](t), t) = b*n[D](t)^2-c*n[D](t)-e*n[D](t)*n[T](t); why dsolve({s1, s2,n[T](0)=0}) gives error?

Dear all,

Thank you to help with the Fourrier serie of:

 f:=t->piecewise((-tp/2<=t and t<-b[0]/(2*Rs),0),(-b[0]/(2*Rs)<=t and t<=b[0]/(2*Rs),ix/b[0]),(b[0]/(2*Rs)<t and t<ty-b[0]/(2*Rs),0),(ty-b[0]/(2*Rs)<=t and t<=ty+b[0]/(2*Rs),-ix/b[0]),(ty+b[0]/(2*Rs)<t and t<=ty+tp/2,0));

ix:=10: Rs:=73.0e-3: b[0]:=Rs*4*Pi/180: b[t]:=Rs*6*Pi/180: ty:=10*Pi/180: tp:=10*Pi/180: plot(f(t),t=-tp/2..ty+tp/2,title=`signal to analyze`);

Thanks

 

 

 

Hi there, Here is my problem : I'm trying to represent ( and animate ) the surface of a vibrating circular drum using plot3d. Let O be the center of the drum, the function "u" I found gives the height (z) of a point on the drum located at a distance r from O at t ( time ) in cylindrical coordinates ( u does not depend on theta). So what I'm basically trying to do is to plot the surface given by the equation z = u(r,t). So far I've failed to do so using plot3d. Could someone here help me with this ? Any help will be greatly appreciated ! Thank you. Tiilt

I have got two columns of data X and Y. if i know the data would possibly fit a function with form : y=ax^n+bx+c, how could i extract the values of a, b and n? Also, how to get the R squared value for the curve fitting.

I use D[ ] to get partial derivatives,

as follows,I donot know is it right?

w := proc (x, y) options operator, arrow; A*(x^4-2*L*x^3+L^3*x)*sin(n*y/R) end proc

t4 := (D[`$`(1, 4)](w))(x, y)+2*(D[`$`(1, 2), `$`(2, 2)](w))(x, y)+(D[`$`(2, 4)](w))(x, y)

If we have three coins. Then the probability of getting three heads or three tails is:

0.5^3 + 0.5^3 = 0.25

Now, what is the probability of getting three heads or three tails when the three
coins are correlated with correlation coefficient p ??

i want someone to help me with this intergration w := (int(K/(y-y1), y = -s .. s))/(4*Pi) he want to know if y1 is between s and -s ,while y1 really exist between s and -s thanks

a:=["34mt5","tru532","64E22N"]

I thought this command worked on Lists.

Select(HasDigit,a)
    Error, (in StringTools:-Select) second argument must be a string

So then I thought maybe map might work

map(HasDigit,b)
     [true,true,true]

okay closer. 

Select(map(HasDigit, c), c)
     Error, (in StringTools:-Select) second argument must be a string

Can't figure out how to get around that string problem

I noticed that if I use add instead on using an integral int I dont get the same value. why ??

restart:
E := 7:   p := .5:
add(p^n*2^(n-1), n = 1 .. E)-p^E*add(2^(n-1), n = 1 .. E);
evalf(int(p^n*2^(n-1), n = 1 .. E)-p^E*(int(2^(n-1), n = 1 .. E)), 5);

Dear reader,

For a concept evaluation I need a system of 13 equations to be solved. Not necesserarily explicitliy, it would be sufficient for me just to see dependencies between variables. However either me or Maple or both are incapable of doing so. I am using Maple 13 by the way.
