Definite Integrals (Level: APC)

This podcast explains how to evaluate definite integrals at given limits of integration, and how this idea relates to finding the area under the curve when a function is graphed.

Indefinite Integrals (Level: APC)

This podcast introduces integrals with the idea "un-doing" a derivative, and then works several examples based on the reverse of the power rule.


video

Derivatives and Max/Min (Level: APC)

This podcast explains how to apply your understanding of derivatives to the problem of finding the maximum or minimum value of a function.


video

Chain Rule and Power Rule (Level: APC)

This podcast introduces how to perform derivatives for some more complicated functions, specifically how to use the chain rule for derivatives of composite functions, and how to use the product rule for the derivative of the product of two functions.


video

Other Common Derivatives (Level: APC)

This podcast introduces common derivatives that can't be performed with the power rule, such as derivatives of some trigonometric, exponential, and logarithmic functions.


video

Derivatives and Power Rule (Level: APC)

This podcast introduces the concept of derivatives, at a depth appropriate for students beginning a calculus-based physics course. This includes a brief description of what a derivative means, and how to find derivatives using the power rule.

Review Blast: PV Diagrams (Level: APB)

This podcast is a very quick review of how to use PV (pressure-volume) diagrams to find temperature at a state, work done during a process or cycle, and change in internal energy during a process or cycle.

Review Blast: 1st Law of Thermodynamics (Level: APB)

This podcast is a very quick review of heat and work as ways to transfer energy into or out of a system, along with rules for when heat and work should be treated as positives or negatives when problem-solving.
