This is not really the next part in my randomness series, but more of an aside.  I used Maple's embedded components to use the Lotto649 drawing data from my last post to create a historical lottery simulator.  Basically, you fill in your prefered numbers, and it simulates you playing the lottery in every draw since 1982.

Is there a way to plot a graph in a fliped way.

I tried to do this using Vectors. But this is not so easy.

plot(Vector(70,x->sin(x/10),Vector(70, x->x+1/10));

plot(sin(x),x=0..7)

>f:=x->(1/sqrt(1+x^3));  I typed this function into Maple, but I keep getting: Error, missing operator or ';'. I'm not sure what I'm missing!

Dear primers,

i read in a list of data (which are called roi), then i would like to fit these data (done in this case by a spline function) and compute the values for y=0.3.
for some reason, maple (i am using maple14) gives me only one value instead of two.

i would be happy if somebody could give me a hint how i get both values.

How does one select rows of a Matrix with say column three having values less than 4?

If for example,   

a:=Matrix(1..5,1..5,rand(1..10)):

One way that I know of is to first convert the Matrix to a listlist

b:=convert(a,listlist):
and then you can use
c:=select(b->b[3]<4,b)
then
d:=convert(c,Matrix)

Is there a way to that without all the conversions?

Hello,

I was following the Getting Started tutorial wher it shows how to do a Taylor series expansion about z=2, for a 4th degree poly.  Maple returns

error, unable to parse 'mverbatim'

Further in the tutorial it asks me to type (x+2y)^3 when upon pressing enter, it returns the same error.

What can be done to correct this error?

Thanks,

Cary M.

Is it possible to construct a fairly complex Punnet square inheritance matrix in Maple 13?

Suggestions and examples or urls would be appreciated.

Cheers

I was wondering how to find the distance between 2 points on Maple 13. For example points (-1,3) and (4,-2).

the problem is as follows:

if((a>0) and (b>0) then (c:=2*a, d:=3b, e:=9b.....)

elif ((a<0) and (b>0)) then (c:=.., d:=..., e:=....)

elif.....

.....

else c:=..., d:=..., e:=...

end if

i know i have the if conditions right, but not sure about sequential conditions..what is the correct syntax for this??

I'm getting errors like parse errors, unterminated if, and invalid sequence (on the :=)...

array.mw

if I assign an array to the variable name x via another named array (A) then if I change all of A, x remains unchanged. this is what I'd expect

however if I change just one element of A then x also changes

this is illustrated in the attached worksheet.

Why is this happening? And how can I stop x from changing if I change a single elment of A?

thanks

Hi

I'm exporting arrays of plots as html (so I get multiple gif files). At the moment I do this off the menus (file\export as) is there a way to write this command at the prompt in worksheet mode?

thanks

I am trying to resize some 2D and 3D plots. I find that the following writes a resized plot to the desktop, but it is cumbersome to use in a program when there are multiple plots:

MYPLOT := %:
     plotsetup(jpeg, plotoutput = "/Users/username/Desktop/EXPAND.jpg",

     plotoptions = "height=1000,width=1000");
MYPLOT;
plotsetup(default)

Click Maple Math, enter x^2/(1+x).   The Preview disappears as soon as I press "/", and the result is not pretty-printed.

Look here concerning this theorem, which states that in any triangle, the three points of intersection of the adjacent angle trisectors form an equilateral triangle, called the Morley triangle.

Help me find all the lines that are carried out from the origin and perpendicular to the 3-D surface.
