When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- How do you find the limit of # (x)(sin(1/x)) # as x approaches infinity?
- If limit of #f(x)=3/2# and #g(x)=1/2# as #x->c#, what the limit of #4f(x)# as #x->c#?
- How do you evaluate the limit #(x^4-10)/(4x^3+x)# as x approaches #oo#?
- How do you find the limit of #(4^y) / (y^2)# as y approaches 0?
- Is the statement "if f(c)=L, then the limit of f(x)=L as x approaches c" a true or false statement?
