residue Returns the residue of an expression at a value.
residue(Expr, Var, Value)
Example:
residue(1/z,z,0)
returns
1
restart Purges all the variables.
restart(NULL)
resultant Returns the resultant (i.e. the determinant of the Sylvester
matrix) of two polynomials.
resultant(Poly1, Poly2, Var)
Example:
resultant(x^3+x+1, x^2-x-2,x) returns -11
revlist Reverses the order of the elements in a list or vector.
revlist(List) or revlist(Vector)

revlist([1,2,3])
returns
[3,2,1]
romberg Uses Romberg’s method to return the approximate value of a
definite integral.
