Logarithmic differentiation is a technique which uses logarithms and its differentiation rules to simplify certain expressions before actually applying the derivative. [ citation needed ] Logarithms can be used to remove exponents, convert products into sums, and convert division into subtraction — each of which may lead to a simplified ...
In these limits, the infinitesimal change is often denoted or .If () is differentiable at , (+) = ′ ().This is the definition of the derivative.All differentiation rules can also be reframed as rules involving limits.
In mathematics, the derivative is a fundamental tool that quantifies the sensitivity to change of a function's output with respect to its input. The derivative of a function of a single variable at a chosen input value, when it exists, is the slope of the tangent line to the graph of the function at that point.

Isaac Newton's notation for differentiation (also called the dot notation, fluxions, or sometimes, crudely, the flyspeck notation [11] for differentiation) places a dot over the dependent variable. That is, if y is a function of t, then the derivative of y with respect to t is
Former Staten Island Congressman Michael Grimm has been left paralyzed from the chest down after falling off of a horse in a freak polo accident in September, pals told The Post on Sunday.. The 54 ...
Social media site Bluesky has gained 1 million new users in the week since the U.S. election, as some X users look for an alternative platform to post their thoughts and engage with others online.
The chain rule can be used to derive some well-known differentiation rules. For example, the quotient rule is a consequence of the chain rule and the product rule . To see this, write the function f ( x )/ g ( x ) as the product f ( x ) · 1/ g ( x ) .
