// Vectors
// Processing provides an easy way to implement vectors in its environment using PVector class.
// It can describe a two or three dimensional vector and comes with a set of methods which are useful for matrices operations.
// You can find more information on PVector class and its functions here. (https://processing.org/reference/PVector.html)

// Trigonometry
// Processing also supports trigonometric operations by supplying a set of functions.
// sin(), cos(), tan(), asin(), acos(), atan() and also degrees() and radians() for convenient conversion.
// However, a thing to note is those functions take angle in radians as the parameter so it has to be converted beforehand.
