Calculus Video 1: The Idea of Limits


 In the Idea of Limits video, we introduce the idea of limits and discuss how it underpins all of the major concepts in calculus.

Calculus Video 2: The Limit Laws

In the Limit Laws video, we introduce the limit laws and discuss how to use them in order to compute limits.

Calculus Video 3: Computing Limits in Practice 

In the Computing Limits in Practice video, we compute some limits in practice; though simple limits of nice (continuous) functions at a point can be computed by plugging in function value at that point, this cannot always be done, notably when the function is undefined at that point. We go through some examples of how to use algebra and factoring to overcome this issue.

Calculus Video 4: Non-Existent Limits 

In the Non-Existent Limits video, we discuss the fact that limits of functions need not necessarily exist. We go through some examples and introduce the idea of left and right-handed limits to give us a computational tool to help determine whether or not limits exist.

Calculus Video 5: Infinite Limits 

In the Infinite Limits video, we discuss infinite limits, which is to say when functions have singularities or, in other words, vertical asymptotes. We give some examples of how to detect and compute these limits in practice.

Calculus Video 6: Continuity and Composition of Limits 

In the Continuity and Composition of Limits video, we introduce another powerful limit law: the composition of limits. We show how this powerful tool can vastly increase the number of limits we are able to compute.

Calculus Video 7: Limits at Infinity  

In the Limits at Infinity video, we discuss the notion of limits at infinity or, in other words, when functions have horizontal asymptotes. In addition to introducing this idea, we also discuss how to compute these limits, notably how our familiar limit laws also apply in this case.

Calculus Video 8: Supplementary Limit Laws 

In the Supplementary Limit Laws video, we discuss a tricky limit law involving how and why we can swap x for 1/x and vice versa when computing a limit. Despite being a bit on the subtle side, this is a powerful technique that can be used to compute some very difficult limits.

Calculus Video 9: The Squeeze Theorem 

In The Squeeze Theorem video, we discuss the Squeeze Theorem which is a theoretical tool that nonetheless gives us a lot of computational power. In a nutshell, it allows us to leverage a clever use of inequalities to compute limits that we otherwise could not be able to deal with.

Calculus Video 10: The Intermediate Value Theorem

In this video, we discuss the Intermediate Value Theorem which is a fact that governs the behavior of continuous functions. This is an important theoretical fact and is one of the most important properties of the real numbers themselves. On the other hand, this theorem can also be used as a tool to determine when and approximately where potentially very complicated functions have roots.
