Limits and Derivatives

The function limit computes limits of expressions in a single real variable. If p is an expression depending on the free variable x limit (p,x=a) returns the limit of p as x tends towards alimit (p,x=a, right) returns the limit of p as x tends towards a+limit (p,x=a, left) returns the limit of p as x tends towards a-limit (p,x=infinity) returns the limit of p as x tends towards +∞limit (p,x=-infinity) returns the limit of p as x tends towards —∞limit (p, x=inf inity, real) returns the limit of p as
