Three (maybe four) major ideas dominate this unit:

**The Chain Rule**as a concept is essential to extending calculus to context based situations.**Implicit Differentiation**is an application of the Chain Rule that allows us to solve problems that would otherwise be impossible to solve.**Related Rates**help us understand how more than one quantity are intertwined with one another and we need to use both the chain rule and implicit differentiation to uncover new ideas.- (bonus) Also, organization of information and notation are more important than ever!

In an effort to support the learning that is happening in class, these three videos will provide the **conceptual understanding** behind these Calculus ideas and also provides several examples of how to use them in our course, this is **procedural** **fluency** which is just as important as concept understanding.

## The Chain Rule

Work to understand how the notation of d/dx is similar to dy/dx. Along with an understanding of fractions, this is a key idea in Calculus.

## Implicit Differentiation

Think about how the Chain Rule is being applied to each situation.

When solving these problems, they get easier the more you work to understand them. STAY ORGANIZED!
