Talk:Formula

message: Is this a disambiguation page? It has the template and the alternate meanings, but what the heck? It seems like it was written by a high-school Chemestry teacher or something. Eww. Who wrote this? Is anyone going to step in and improve it? I'd rather not intrude, though I guess if I have to eventually... =/ Matt Yeager 06:26, 3 December 2005 (UTC)
replies: text: It seems that the word "formula" - even in the limited context of mathematics - has multiple meanings. The basic meaning is akin to "shorthand". The other meaning is like in the conversation: "how do you calculate the volume of a sphere?". Answer: "you may compute the volume using integral calculus, but there is a formula for that". This is probably why the sphere volume formula is included at all in this article. Would it be a suggestion to write a short abstract article on "formulae in mathematics and science", which only says that a formula is a shorthand, and then to expand in separate articles on formulae in mathematics and (most) other sciences, and formulae in chemistry?

text: The formula  V = \begin{matrix} \frac{4}{3} \end{matrix} \pi r^3  is independent of the used units. For example, if you insert numbers with r in cm then you get V in cm3 after taking the cube, and if you insert r in mm then you get V in mm3. The same applies to E=mc2 and other physical formulas. You don't replace the variable with a number only. You replace it with a number and unit of your choice, and the unit is included in the operations. When geometry is not applied to the physical world, it is common to not use units for length, area, volume. For example, the radius of a circle may simply be given as 1 and it's area as π. This may assume some underlying coordinate system. PrimeHunter 15:13, 8 September 2007 (UTC)
thread_title: This page needs improvement

message: The disambiguation page says: "See [formula] for an account of the concept in mathematics and the sciences". I think this is a good description of what this page seems to be trying to achieve, and so perhaps it should be renamed to reflect this.

replies: text: Beware though that chemistry is a branch of science that uses formulae in an entirely different way (e.g. structure formulae). Rbakels (talk) 12:08, 26 April 2012 (UTC)

thread_title:  Should this page be renamed? 

message: This would be a good addition on this page:
e.g.
The area of a circle (A) is p * r^2.
So A = p * r^2
If we know the radius, it is easy to find the area using this formula. However, if we know the area and want to find the radius, rearrange the formula to make 'r' the subject.
A = pi * r^2
[Start by dividing both sides by pi]
A/pi = r^2
[Then take the square root of both sides] 
r = sqrt (A / pi)

thread_title:  Changing the subject of a formula 

message: As far as I know, the word "formula" is used because it is the Latin deminutive of "forma", I guess because a formula is in essence a shorthand (for something that could have been expressed in ordinary language as well).
I added this comment to the dicussion page rather than the article itself  because I am not entirely sure.

thread_title:  English 

message: The article states apodictically, "Expressions are distinct from formulas in that they cannot contain an equals sign (=)." The citation is not practically verifiable; it refers to a 228-page book without supplying a page number. But here is an indisputable example of an expression containing an equals sign, taken from :
:For a value  in  and an event , the conditional probability is given by  P(A \mid X=x) .
In elementary mathematics, most expressions, such as ax+by+c or x^2-1, are not commonly referred to as formulas, but not because of the absence of an equals sign. While it is true that in informal mathematical parlance equations are not commonly referred to as "expressions", this also applies to inequations and in most elementary contexts to implications and other logical formulas. But why should this be mentioned here, in the article Formula? I propose to delete the statement. Objections?  --Lambiam 10:41, 26 May 2023 (UTC)
