## At A Glance

### Limit basics

Limits are the core tool that we build upon for calculus. Many times, a function can be undefined at a point, but we can thinking about what the function "approaches" as it gets closer and closer to that point (this is the "limit"). Other times, the function may be defined at a point, but it may approach a different limit. There are many, many times where the function value is the same as the limit at a point. Either way, this is a powerful tool as we start thinking about slope of a tange...

Limits are the core tool that we build upon for calculus. Many times, a function can be undefined at a point, but we can thinking about what the function "approaches" as it gets closer and closer to that point (this is the "limit"). Other times, the function may be defined at a point, but it may approach a different limit. There are many, many times where the function value is the same as the limit at a point. Either way, this is a powerful tool as we start thinking about slope of a tangent line to a curve.If you have a decent background in algebra (graphing and functions in particular), you'll hopefully enjoy this tutorial!
