Small Circle Symbol in Math: Composition!
The small circle symbol (∘) in mathematics is widely used to denote function composition. It is an operator that combines two functions into a single function, where the output of one function becomes the input of the other.
The small circle symbol represents the composition of functions in mathematics. For example, if f and g are functions, then their composition is written as (f ∘ g)(x) and is defined as f(g(x)).
Here’s how it works:
The order of functions is important; (f ∘ g)(x) is generally not the same as (g ∘ f)(x). The small circle symbol is pivotal in streamlining complex function operations into a single, manageable expression.
