# How do you compute the dot product to find the magnitude of #u=<-5,12>#?

You cannot compute the dot product with only 1 vector. You do not need the dot product to find the magnitude of the given vector anyway.

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.
