From 0 to 20 degrees, tan() is also roughly the same as sin(), so you
throw that page out of your CRC math tables.

My copy of the CRC Math Tables was purchased by my mother in 1939 when
she was a freshman math student at Berkeley. Can't tear pages from an
heirloom. If I did she'd notice and ask me about it.

My copy of school log tables from 1964 have THURSDAY written in large
capital letters on the back. It was the maths lesson following afternoon
break where I'd concussed myself somehow and I kept asking my classmate
what day it was until he eventually wrote it down.

He eventually realised something was wrong and I was taken home where I
read the evening paper about 10 times, and went up to see if my bike was
OK after my "fall" about 20 times before I eventually was taken to
hospital and kept in for a couple of nights :/
