Homework Help: Math

I have a TI-83 graphing calculator. How do you graph a polar equation on this calculator. Also how would I graph lim 5/x-2 x-->2 in order to find the limit?

Press [MODE] and there should be a place to select [POL] for changing the graphing mode to polar.

To find the limit simply graph the equation as normal. Press [TRACE] and type something like 2.000001 and you'll get very close to the limit.
