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.

BTW, funny how the numbers don't change with time. Must be some sort of
universal attribute.

I got my copy in 1965 when I started my first attempt at college. By the time of my college restart in 1977, almost everything of use in there could be found in a pocket calculator. Now the calculator function of my cell phone does all that work.

Now even the trig relations and integral equivalents are built into free online pages.
