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 :/

The last hard fall I had skiing included a concussion - a whiplash onto frozen surface early on a spring-skiing day after yesterday's wet slop froze overnight. Even worse - I had borrowed my son's snowboarding helmet, but decided not to wear it that day because it had been uncomfortably hot the day before.

for some reason, this is starting to look like one of those old-fashioned skiing threads

OK, let's keep it going. Although I always wore a helmet when I was
motorcycling and bicycling, and actually have a ski helmet, I don't wear
one skiing. The myriad falls I've had involved body parts not protected
by a helmet, so so far, so good.

Maybe I'd wear it if I painted it day-glo orange...
