[MUSIC] Week 1 has ended. 
Week 2 begins right now. 
I am just wondering, where are we? What 
are we doing? Well, last week, during 
week 1, we introduced Functions and 
Limits, and this week, during week 2, 
we're going to go deeper into those. 
Topics. 
We're going to go deeper into Functions 
by looking at Continuity. 
What does it mean for a Function to be 
continuous? And we're going to study 
Limits by playing a bunch of variations 
on the definition of Limit. 
We're going to look at limits that 
involve data from just one side and 
limits that involve infinity. 
We'll wrap up week two by reviewing just 
slope of straight lines. 
That sets us up for Week 3. 
What happens in week 3? We're going to 
take Slope and Limits and combine them to 
get Derivatives and we'll be studying 
Derivatives from Weeks 3 all the way on 
to Week 11. 
So this is good news. 
If you're really bummed out about all the 
limit stuff, we just got 1 more week of 
limits, and next week we start a brand 
new topic, derivatives. 
On the other hand, if you're really 
loving this Limits stuff, I've got good 
news for you, too. 
Limits are going to play a behind the 
scenes role in everything we do, from now 
until the end of the course. 
Now hang in there, and good luck.
