MathsCasts: Logarithmic Differentiation: Typed
Loch, B. (Birgit) (2011)
This screencast explains how differentiation requiring combinations (or multiple uses) of the product, chain and quotient rules can be made simpler by using logarithmic differentiation. This method relies on log rules to simplify a function before taking a derivative. This particular screencast shows typed explanations. Please compare to the other screencast going through the same example but with handwritten explanations, and send us feedback on which explains this concept better.
