4 Μαρ 2018 · Pi notation provides a compact way to represent many products. To make use of it you will need a “closed form” expression (one that allows you to describe each factor’s value using its factor number) that describes all factors in the product.
The following is a list of significant formulae involving the mathematical constant π. Many of these formulae can be found in the article Pi, or the article Approximations of π.
The following will be counted as Level 2 (or higher) mathematics: • application and understanding requiring choice of data or equation to be used • problem solving involving use of mathematics from different areas of maths and decisions

There are two main ways orbitals can overlap when forming a bond: directly, leading to the forming of a sigma (σ) bond and sideways, leading to the forming of a pi (π) bond. We will use the simple example of bonding in an oxygen molecule to show the forming of sigma and pi bonds.
