#### Linear Approximation | Formula & Example

Linear Approximation | Formula & Example In mathematics, a linear approximation is an approximation of a general function using a linear function (more precisely, an affine function). They are widely used in the method of finite differences to produce first-order methods for solving or approximating solutions to equations. Given a twice continuously differentiable function {\displaystyle f} of one real variable, Taylor’s theorem for the case {\displaystyle n=1} states that {\displaystyle f(x)=f(a)+f'(a)(x-a)+R_{2}\ } […]

#### What Is An Alkyl Group? Uses

Alkyl Group | What Is An Alkyl Group In organic chemistry, an alkyl group substituent is an alkane missing one hydrogen. The term alkyl is intentionally unspecific to include many possible substitutions. An acyclic alkyl has the general formula CnH2n+1. A cycloalkyl is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula CnH2n-1. Typically an alkyl is a part […]

#### What Is Electronegativity Trend? Example

Electronegativity Trend | What Is Electronegativity Trend? Electronegativity Trend, symbol χ, is a chemical property that describes the tendency of an atom to attract a shared pair of electrons (electron density) towards itself. An atom’s electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged […]

#### What Is A Hydroxyl Group? Properties

Hydroxyl Group | What Is A Hydroxyl Group A hydroxyl group increases the ECL value of a fatty acid greatly, especially on polar columns, and if the hydroxyl group is derivatized, the nature of the derivative has a profound effect on the elution profile for different isomers. The hydroxyl group is a functional group consisting […]
