What is the difference between equations

You wouldn't say the "force formula", but the "force equation". They can have an infinite number of solutions. An equation is a relationship that defines a restriction.

Not exactly rectangle. Can be rectangular prism or whatever. According to my 2ndary school teachers, what you provided is a formula Conclusion : I'd say it really depends on the context. If you define equation as a statement with an equal sign, then every formula with an equal sign is an equation Btw it seems on wiki that there are no inequalities that are formulas.

One way to answer this question has been developed in the first and second courses of U. While at the beginning of the the second course, the following sentence summarizes that the relationship is between two or more variables:.

A formula is an equation that states a relationship between two or more variables. Sign up to join this community. The best answers are voted up and rise to the top. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

There are no equal signs! This is what makes writing expressions different from writing equations. Both equations and expressions can have variables, coefficients , whole numbers, decimals, exponents, addition, subtraction, multiplication and division.

But unlike expressions, algebraic equations must always include an equal sign:. As you can see in the simple equations above, there are two sides of the equation: a right and a left side.

So technically, an equation is made of two expressions. The equal sign establishes the two sides of the equation as equivalent expressions. However, each alphabet will correspond to one number. A function, on the other hand, is in much more complex than an equation. A function is used to denote a relation between a set of inputs and a set of corresponding outputs. Essentially, an input should give a single output.

A function is a relationship between two variables. As per this function, whatever, the input is, it will give you a single output, which will be the input plus 2. Functions have various applications in mathematics, physics, computer science, etc. They can range from a simple function, as denoted above, to complex formulas or algorithms. A function can be thought of as a machine that gives an output for an input, and that output is somehow related to the input.

A function always has three parts: the input, the relationship, and the output. As stated above, the main difference between an equation and a function is that an equation usually has only one input that will give lead to the expressions being equal. Whereas, a function has various inputs, each of which will give a output.
