Why it's important
You can use the quotient rule to answer questions like:
Find f'(x) when f(x) = (3 + x2)/(x4 + x).
What it is
I recite this rhyme to remember the quotient rule:
Low Dee High minus High Dee Low
Draw the Bar and Square Below
f'(x) = [low * dee high...
Rules for Differentiation
Here is a list of general rules that can be applied when finding the derivative of a function. These properties are mostly derived from the
limit definition of the derivative.

see quotient rule
see chain rule
Quotient Rule Explanation
Similar to product rule, the quotient rule is a way of
differentiating the quotient, or division of
functions. The quotient rule is defined as the quantity of the denominator times the derivative of the numerator minus the numerator times the derivative of the denominator all over the denominator squared.
