Curious as to why the whole line, during an animatecurve plot, "wiggles" as it's being animated. 

A simple example

plots[animatecurve](sin(x),x=-Pi..Pi,frames=100);

Why is that?

I'm spliting up a number into a list but I'm not sure if this is the best way.

a:=74.367854;

b:= convert(a, string);

with(StringTools);

c:=Select(IsAlphaNumeric,b);

d:=Explode(c);

e:=seq(parse(d[i]),i=1..nops(d));

                                            7,4,3,6,7,8,5,4

a:=seq(1/x,x=1..10);

b:=evalf(a,4);

c:=matrix(2,10,[[a],[b]]);  

How do I swap this to a 2 column 10 row matrix.

I have a rather simple equation describing a predator prey model  p=900+c*e^(t/2)

I want to plot the equation for various values of c.  How do I set maple to plot it? 

Recently I came across a page that was working with ifactor and it seems op now handles the operations a bit different now. 

ifactor(3^43+1);

       (2) (82064241848634269407)

a:=op(2,%):

ifactor(3^41+1);

       (2)(270547105429567)(33703)

b:=op(2,%):

c:=a*b;

     (82064241848634269407) (271547105429567)
