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 k such that the line is tangent to the graph of the function function: #f(x) = x^2 - kx# and line: y=4x - 9?
- What is the slope of the line normal to the tangent line of #f(x) = 1/x+x^3 # at # x= 2 #?
- Differentiate #-x^2-2x-2# using first principles?
- How do you find the instantaneous rate of change of the function #f(x)=x^2+2x# when x=0?
- What is the equation of the line normal to # f(x)=-sqrt((x-5)(x-2)# at # x=6#?
