Question

Define: formula in Algebra

Answer 1

I would say that a formula is an equation that relates variables (known as proportion some times)
Im not sure if that answers your question hehe

Answer 2

I should say different variable

Answer 3

Sounds good :)

Answer 4

\(\large e = mc^2\) is a formula or equation ?

Answer 5

Both, since a formula is an equation.

Answer 6

I have not really thought of this before, since knowing what a formula is in a way also saying what a formula isn't. In the context of an algebra class it's probably a wise idea to make the distinction between an expression and an equation.

But I think that there is a difference between an equation and a formula. For example, what is a^2+b^2=c^2? That is a formula. Now what if I tell you sin(x)=x ? That is an equation. The difference being that a^2+b^2=c^2 is very much like a law of physics, it's provable, and shows relationships between known quantities, those being the hypotenuse and the legs of a right triangle. Now sin(x)=x is an equation because it can be evaluated based on its truth value and in a sense is the exactly the same as saying x=0. There's not really the same level of being a "formula" going on here because we don't really even know what sin(x) or x are supposed to represent, it's simply an equation that has only one answer. Meanwhile a formula like A=pi*r^2 has no answer.

That's what I think of when I think of the difference between an equation and a formula, and I think that's what @ganeshie8 was trying to say. A formula is an equation, but an equation isn't necessarily a formula. @skullpatrol

Answer 7

How can equality not be symmetric when dealing with real numbers?

Answer 8

$$\Huge formula = equation$$
$$\Huge equation \neq formula$$

Answer 9

No, I'm saying something more of the case:

All squares are rectangles.
Not all rectangles are squares.

Answer 10

All squares are a special case of a rectangle.

Answer 11

Sure, so are you saying we should write: \[\LARGE Square = Rectangle\] \[\LARGE Rectangle \ne Square\]

Afterall, how can equality not be symmetric when dealing with real polygons?

Answer 12

Formulla is a law u follow to find something .
its like sets of theroms / lemas / propositions
lead to conclusion or forula or law or what ever u wanna name it

Answer 13

equation is a statment that have too sides and a logic sighn ( never heard of a variable as a condition hmmm but that what is known )

Answer 14

two sides *

Answer 15

A formula is an equation that states a rule about a relationship.

Answer 16

All equations are formulas and all formulas are equations.

Answer 17

formula is a rule .which is predefined.i think

Answer 18

It states a rule about a relationship in the form of an equation.

Answer 19

yeah.a set form of words, as for stating or declaring something definitely .its a method or technique to get the accurate answer

Answer 20

relationship btw system of equation?

Answer 21

A reference for performing calculation

Answer 22

An equation says that two things are equal

Answer 23

and also predefined function or expression or fact

Answer 24

A method or technique used to get a accurate result or output
