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.

- A triangle has corners at #(2 ,4 )#, #(7 ,6 )#, and #(4 ,9 )#. How far is the triangle's centroid from the origin?
- Let M and N be matrices , #M = [(a, b),(c,d)] and N =[(e, f),(g, h)],# and #v# a vector #v = [(x), (y)].# Show that #M(Nv) = (MN)v#?
- A line passes through #(9 ,5 )# and #(2 ,3 )#. A second line passes through #(2 ,8 )#. What is one other point that the second line may pass through if it is parallel to the first line?
- What is the equation of the line perpendicular to #y - 4 = 0# and passing through (-1, 6)? Please show working.
