nouns & verbs



Now I think I understand that the need for the so-called verb function:

 (%i1) :lisp(trace $cos);

 (%i1) ''cos(0);
 0> Calling ($COS 0) 
 <0 $COS returned 1
 (%o1) 1

Hermite doesn't have a verb function:

 (%i2) ''hermite(1,x);
 (%o2)  hermite(1, x)

 (%i3) hermite(1,x);
 (%o3) 2 x
