gollark: Yes, which is mildly more annoying than saying τ radians.
gollark: τ radians is a full turn of a circle. 1/4τ is a quarter circle. This is somewhat easier than with pi.
gollark: Radians!
gollark: I mean, you can get it from a circle; tau is the *radius*/circumference ratio.
gollark: There are formulae for both, IIRC.
