From Wikipedia, the free encyclopedia
There are two kinds of mathematical equations:
- The kind of equation that is either true or false; these are also called identities
- The kind of equation that lets you calculate the value of one or several variables. The equation is only true if the variable(s) have that value.
The second kind is often used to solve problems in which you have to know the value of some variables. For example, if 2x = 8, x = 8 / 2 = 4.
Types of equations[change | edit source]
- An algebraic equation is an equation in which both sides are polynomials. These are further classified by degree:
- A Diophantine equation is an equation where the unknowns are required to be integers
- A differential equation is a functional equation involving derivatives of the unknown functions
