formula

[Offroad]

Dear teachers and friends...

Could you shed some light on this?

The thesaurus defines 'formula' as

n. pl. for·mu·las or for·mu·lae (-l)
1. a. An established form of words or symbols for use in a ceremony or procedure.
b. An utterance of conventional notions or beliefs; a hackneyed expression.

2. A method of doing or treating something that relies on an established, uncontroversial model or approach: a new situation comedy that simply uses an old formula.
3. Chemistry a. A symbolic representation of the composition or of the composition and structure of a compound.
b. The compound so represented.

4. a. A prescription of ingredients in fixed proportion; a recipe.
b. A liquid food for infants, containing most of the nutrients in human milk.

5. Mathematics A statement, especially an equation, of a fact, rule, principle, or other logical relation.
6. Formula Sports A set of specifications, including engine displacement, fuel capacity, and weight, that determine a class of racing car.

I dispute the use of 'formula' as being an equation. Does this make any sense to you?

Thank you very much.

Correctly the word 'use' is used and not 'usage'.

It is nonsense. All formulas are equations.

What exactly are you talking about?
Are you asking whether all equations are formulas and vice-versa?
Regarding the 5th meaning above - mathematics, I see the idea of a formula is different from the idea of an equation. However, in everyday usage, the two can be interchanged whenever there is no home for misunderstanding.

Oh, never mind, nonsense.

That is not nonsense. Only the difference is not so important in everyday
language use. But of course a formula is not always an equation. Neither an equation is always a formula.
