Or, for access to this single video, go to: http://www.mindbites.com/lesson/852-calculus-differentiating-logarithmic-functions In this lesson, you will learn how to take the derivative of logarithmic functions. While the derivative of ln x is 1/x, this lesson will teach you how to find the derivative of a logarithmic function when the base is different (e.g. when you need to calculate the derivative for an equation like y=log (base b) x). In explaining how to differentiate these types of problems, Professor Burger will show you how to arrive at the answer and why it is correct. He will also walk through how to manipulate the log expression into an exponential function such that you can solve for the variable exponent using natural logs. You will also go through more advanced problems that involve differentiation of logs in addition to usage of the chain rule, the product rule, and trig functions. Taught by Professor Edward Burger, this lesson was selected from a broader, comprehensive Calculus course.
