can't read them, some parts too small

dont u just plug in PI for part C.. lol

when you want to evaluate a limit: first just try plugging the actual value into the expression. If you don't get any whammies, you are done. Whammies are typically when you get stuff like a divide by 0 conflict. Then you have to try cancelling and other tricks.

Problem C and D are of the simplest kind, they you can just plug in the values into the expression and simplify.

i dont have to do anything to c or d? it seems too ez to just plugin the values?

ur gonna have a 0 in the denominator if u straight up plug it in for part D.

multiply by conjegate?
