Unfortunately, we can only use the logarithm laws to help us in a limited number of logarithm differentiation question types. Implicit derivative of e^(xy^2) x - y Building the idea of espilon delta definition This original Khan Academy video was translated into isiZulu by Wazi Kunene. Derivative of y = ln u (where u is a function of x). It requires deft algebra skills and careful use of the following unpopular, but well-known, properties of logarithms. Though the following properties and methods are true for a logarithm of any base, only the natural logarithm (base e, where e The Logarithmic differentiation exercise appears under the Differential calculus Math Mission on Khan Academy. Learn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more.
