How do you graph the point #R(-7/2, 1050^o)#?

Answer 1

see below

First, find the co-terminal angle for #1050^@#. Note that if you start from the positive x-axis and go counterclockwise (standard position) then you will go around the circle twice and then terminate at #330^@# which is the co-terminal for #1050^@#.

Since r is negative #(-7/2)# it means that we have to plot the point on the opposite ray from #330^@# which is the ray #150^@#.

So halfway between circle number 3 and 4 plot the point on the ray #150^@#.

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.
