Taylor expansions

Back in my day we had books filled with tables of that shit.

Just compute an infinite sum, unless you are a wilderjew, then sin doesn't exist

With shifts

draw a unit circle

slide rule

sin(x)=x
cos(x)=x+π/2

Care to elaborate?

How did you use these? I've heard they exist but can't find anything on how these books were used

The books were filled with simple tables for roots, sines, cosines, logs etc. I'd scan a few pages for you to see but I'm away from home during work days. There are samples of them online like pic related.
