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.

- Distance travelled by a car in feet is given by: #t^3-9t^2+24t+5#, how do you determine the average velocity over the interval (1,2)?
- How do you find the equation of the tangent line to the graph of #f(x)=x^2+3x-7# at x =1?
- How do you find the derivative of #f(x)= x^2 -5x + 3 # using the limit definition?
- What is the slope of the line normal to the tangent line of #f(x) = x^2-3sqrtx # at # x= 3 #?
