## AP Calculus AB / BC Big Idea Review - Limits

Introduction A limit is the value that a function takes as it approaches a certain point. For continuous functions, this is the value of the function itself. However, for discontinuous functions, limits can have interesting implications. In other words, if the function is continuous: $$\lim_{x \to a} f(x) = f(a)$$ When a...

## 3 Reasons Why Calculus Is so Hard

The derivative of its difficulty is also zero, so it will always be this hardCaptain Calculus So you are a pre-med or engineering student stuck in a Calculus class and just had your mind blown to its limits (no pun intended). Most students start scratching their heads when limits become derivatives. Then when derivatives...

## AP Calculus BC Review Question 1

A review by Omninox of an AP Calculus BC question Now we shift our focus from the most recent reviews of social subjects to mathematics. Specifically, we will cover a topic of Calculus BC. Now, BC has a mix of Calculus AB content and new BC material, but the majority of the questions deal...

## What is a Derivative?

Understanding this concept is half of Calculus, and it has vast implications What if I told you that you have had the fundamentals on how to take a derivative since Algebra? You would probably laugh at me and call me crazy, and you would be right. Really though, the formula for a derivative is...

## What is a Limit?

One of the first concepts learned in Calculus is also one of the more confusing ones Simply put, a limit is the value a function takes as x approaches some number (usually a). In the image above, x approaches 2. The word “approaches” is very important because x can never equal the limit. This...
