# Documentation

rotateV :: Float -> Vector -> Vector Source #

Rotate a vector by an angle (in radians). +ve angle is counter-clockwise.

angleVV :: Vector -> Vector -> Float Source #

Compute the inner angle (in radians) between two vectors.

normalizeV :: Vector -> Vector Source #

Normalise a vector, so it has a magnitude of 1.

unitVectorAtAngle :: Float -> Vector Source #

Produce a unit vector at a given angle relative to the +ve x-axis. The provided angle is in radians.
