The formula e pagëzimit (English: baptismal formula) is the oldest written document with a writing in Albanian which has been found. The document is “Codex Ashburnham” dated November 8, 1462, and it contains various notes on Albania written in Latin by Archbishop Pal Engjëlli. [1] [2] The sentence in Old Albanian is:
The first certain document in Albanian is the "Formula e pagëzimit" (1462) (baptismal formula), issued by Pal Engjëlli (1417–1470); it was written in Latin characters. [13] It was a simple phrase that was supposed to be used by the relatives of a dying person if they could not make it to churches during the troubled times of the Ottoman ...
Drilling Formula Sheets is a set of Drilling Formulas used commonly by drilling engineers in the onshore and offshore oil drilling industry. They are used as part of a key piece of engineering work called Well Control .
In mathematics, Vieta's formulas relate the coefficients of a polynomial to sums and products of its roots. [1] They are named after François Viète (more commonly referred to by the Latinised form of his name, "Franciscus Vieta").
Viète's formula may be rewritten and understood as a limit expression [3] = =, where = = +.. For each choice of , the expression in the limit is a finite product, and as gets arbitrarily large, these finite products have values that approach the value of Viète's formula arbitrarily closely.
Replacement: (i) the formula to be replaced must be within a tautology, i.e. logically equivalent ( connected by ≡ or ↔) to the formula that replaces it, and (ii) unlike substitution its permissible for the replacement to occur only in one place (i.e. for one formula). Example: Use this set of formula schemas/equivalences: ( (a ∨ 0) ≡ a ).
Mathematical formulas are often algebraic, analytical or in closed form. [5] In a general context, formulas often represent mathematical models of real world phenomena, and as such can be used to provide solutions (or approximate solutions) to real world problems, with some being more general than others. For example, the formula
Example: The final value of a 7-year annuity-due with a nominal annual interest rate of 9% and monthly payments of $100 can be calculated by: FV due ( 0.09 12 , 7 × 12 , $ 100 ) = $ 100 × s ¨ 84 ¯ | 0.0075 = $ 11 , 730.01. {\displaystyle {\text{FV}}_{\text{due}}\left({\frac {0.09}{12}},7\times 12,\$100\right)=\$100\times {\ddot {s ...
