You can find numerous online resources to help you learn the math we are covering in this course. One YouTube math channel I like is PatrickJMT. He has an entire playlist on derivatives, which you can find here.

For example, here are a couple of his videos on the topic we just covered–finding derivatives using the power rule:

## Announcement

The college is closed on Monday (Sept 25), so our next class meeting will be next Wednesday (Sept 27). Please work on the open WebWork sets in the meantime:

“Derivatives – Functions” (due Mon Sept 25)

“Derivatives – Power Rule” (due Thurs Sept 28)

## Topics

We found the derivatives of the following power functions ( f(x) = x^n ), and generalized this to the “Power Rule”.

We also introduced the “d/dx” notation for derivatives, and the Sum and Constant Multiple Rules:

Using these rules, we can now find the derivative of any polynomial. For example:

See Sec 3.3 – Differentiation Rules in the textbook for the statements of these rules and additional examples:
