Bases: MomentumAwkward2D

A cartesian 2-dimensional vector

A heavy emphasis towards a momentum vector interpretation is assumed, hence properties like px and py are provided in addition to x and y.

This mixin class requires the parent class to provide items x and y.

r

Distance from origin in XY plane

\(\sqrt{x^2+y^2}\)

r2

Squared r

unit

Unit vector, a vector of length 1 pointing in the same direction

Methods Documentation

absolute()

Returns magnitude of the 2D vector

Alias for r

delta_phi(other)

Compute difference in angle between two vectors

Returns a value within [-pi, pi)

divide(other)

Divide this vector by a scalar elementwise using its cartesian components

This is realized by using the multiplication functionality
