Alternative math

Being politically correct all the time is similar to being brain-dead:

A better abbreviation for sine & cosine

For some weird reason the abbreviation for sine is sin and cos for cosine. This is madness compared to the beautiful and logical abbreviation for tangent and cotangent: tg and ctg respectively.

My proposal:

sine si
cosine csi
tangent tg
cotangent ctg

Quite obviously, I submitted them to my local ISO representative for review.
