From Wikipedia, the free encyclopedia. In calculus, the quotient rule is a method of finding the derivative of a function that is the quotient of two other functions for which derivatives exist.If the function one wishes to differentiate, , can be written as. and, then the rule states that the derivative of is.More precisely, if all x in some open set containing the number a satisfy, and and both exist, then exists as well and.f the function one wishes to differentiate, , can be written as. and, then the rule states that the derivative of is.

A carboxylic acid /ËkÉrbÉkËsÉªlÉªk/ is an organic compound that contains a carboxyl group (C(O)OH). The general formula of a carboxylic acid is RâC(O)OH with R referring to the rest of the (possibly quite large) molecule.Carboxylic acids occur widely and include the amino acids and acetic acid (as vinegar).arboxylic acids react with bases to form carboxylate salts, in which the hydrogen of the hydroxyl (-OH) group is replaced with a metal cation. Thus, acetic acid found in vinegar reacts with sodium bicarbonate (baking soda) to form sodium acetate, carbon dioxide, and water:
The thiol functional group is similar to the hydroxyl group except the oxygen atom in the hydroxyl group is a sulfur atom in the thiol group. Thiol functional group is also known as a sulfhydryl functional group.Thiol functional groups have formula-SH. Molecules that contain thiol groups are also called mercaptans.. Also known as the carboxyl functional group. The carboxyl group is an ester where one substituent R is a hydrogen atom. The carboxyl group is usually denoted by-COOH. This is the general structure of the thiol functional group.
