Function
I need help, I don't know what I did wrong? I plugged it into the equation. I know that I made a mistake for (b) it suppose to be INFINITY but I don't understand what I did wrong in the first part (a)

change to radian mode on your calculator ... you did it in degree mode.

I put INFINITY and -INFINITY but both of these answers are wrong. (Doh)
I thought it will be infinity since it's going to .333333333333333333...etc

0.333333333333333 looks like strong empirical evidence for the limit being equal to 1/3, I would have thought.

(Indeed, see Wolfram|Alpha )
