## Video Transcript

Okay, So after the limit as I could, which is part of a to attend, You know that. So the blue line here is pi over, too. You notice that if we approach from the right hand side, we're going off to infinity, and then if we're approaching X from the left hand side was like, this is the left side. And if we're approaching from the right hand side, we're approaching Megan of Affinity. What? The limits are going off in Cindy and the Infinity. Our limits.
