What is the difference between a formula and a function ?

Hint: Here in this question we have to write the difference between the formula and the function. The formula and function concepts will not come in the same topic. So, by knowing the definition of the formula and function then it will be the difference of the formula and function.

Complete step by step answer:
Here we have to write the difference between the formula and function. To write the difference firstly we have to know about the formula and the function.

Formula: A formula is a statement written by the US and it is used to calculate. Formulas can be as simple or as complex, it depends on the problem or situation. A formula can contain values, references to cells, defined names, and functions. All formulas must start with the equals sign. For example: The formula for the area of the square is given by \[A = {(side)^2}\]. The formula for the perimeter of a circle is given by \[C = 2\pi r\]

Function: A function is a piece of code designed to calculate specific values and is used inside formulas. Functions to sum values, calculate a trigonometric ratio. Additional functions can be defined using Visual Basic. Functions are typed alongside parentheses, where in the arguments if any are listed in between. For example: The value of the function \[\cos ({30^ \circ })\].

Note:As we know that the function of a variable x can be written as \[f(x)\], for this function we can write the formula i.e. \[f(x) = {x^2}\]. This definition of the function is not general, we are considering the function as usual. By defining the both words will be considered as a difference. There is no need to compare the formula and function.
