`animate`, the number of pictures as fourth argument with
`frames=`number,
the remaining arguments are the same as those of the `plot` command,
see section 3.3, p. ??.

Input :

`animate(sin(a*x),x=-pi..pi,a=-2..2,frames=10,color=red)`

Output :

`a sequence of graphic representations of y=sin(`*a*`x) for
11 values of `*a*` between -2 and 2`
