In mathematics, there is something called a formula. It generally refers to an inequality relating one mathematical expression to another. Formulas can be used to find solutions to real-world problems, by imputing, or replacing variables with constants, and then solving the newfound equation. Formulas usually include the following components:
• Usually written in some form of algebraic, analytical, or closed format,
• Are sometimes used to represent models of real world phenomena,
• Include one or more unit(s).
Important Formulas To Know
In mathematics, there are several formulas that are used more than others to a considerable degree. It is good to keep in mind that a mathematical formulas aren’t restricted to fields dealing with numerical problems. For example, a construction worker who was entirely in charge of lowering a bathroom’s sink into the hole in a counter, would have to find the perimeter, in order to know how much cutting he would have to do, in order to make it fit. Here are a few common formulas that are used in varies professions:
• To find the circumference of a circle: 2π x r
• To find the area of a circle: π x r²
• To find the length of a hypotenuse in a right triangle: a²+b²=c²
• To find the area of a square: a²
• To find the perimeter of a square: 4 x a
Here is a visual representation of diameter (d), and radius (r):
In conclusion, formulas are fundamental to our understanding of the world.
