The phrase "a formula of class" is correct and usable in written English.
It can be used in contexts where you are referring to a specific formula that belongs to or is characteristic of a particular class or category.
Example: "In mathematics, a formula of class can help categorize different types of equations based on their properties."
Alternatives: "a class formula" or "a formula belonging to a class".
Under Ed Miliband's leadership, two key figures, the Labour peer Maurice Glasman and MP Jon Cruddas, developed a formula of "conservative socialism" to appeal to working-class voters based on "family, faith and flag".
"There's a misconception that codeine is a weaker formula of the same class of medicine" as heroin, said Dr. George Fallieras, an emergency room physician at Los Angeles' Good Samaritan Hospital.
Since all the mappings which are present in the previous formula are of class C 1, using the usual rules of the differential calculus in Banach spaces, we obtain that Φ is of class C 1.
Given that n stands for "any number," the general formula of this class is therefore CnH2n + 2. Empirical formulas are normally used to represent substances with undetermined molecular structures or substances not made up of normal molecular entities e.g., sodium chloride (table salt), which is composed of ions.
To provide a logic with an algebraic semantics was to interpret its language in a class of algebras, define a notion of satisfaction of a formula in an algebra of the class and prove a soundness and completeness theorem, usually for the theorems of the logic only.
The movies share tried-and-true elements of the Sparks formula: star-crossed love with a hint of class disparity (but no nonwhite characters of any consequence); terminal illness; late-breaking revelations and plot twists.
This formula enabled each vessel to be allocated a total number of Class-A units.
2.4 Trace formulae for perturbations of class (mathbf{S}_m), (mge 2).
Secondly, much more general trace formulae for perturbations of class ({varvec{S}}_m) we obtained in [10].
We also consider connections between multiple operator integrals and trace formulae for perturbations of class ({varvec{S}}_m), where m is positive integer greater than 1. 2.1 A brief introduction to multiple operator integrals.
