Trigonometric functions

Sure loved Algebra back in high school. Did I say I loved fractions too ? Guess that explains being able to use a measuring tape using 16th of an inch and cutting stair treads to the correct size as instructed. Anyone up for 32nd of an inch ? Guess in stair building business 16 is as good as it gets.
At the very least I won’t have to deal with that anymore now – screwing up my cuts and having someone trying to blame me for not cutting to size. Dastardly deeds indeed – all while I was away on stair installations elsewhere.
So much for conservation of wood and trees. Someone must really screwed up when they think money grows on trees and then cuts them down like there’s no tomorrow. Drugs anyone ??? Been there done that working around people doing that stuff while at work. Thanks but no thanks. Not my version of paradise and spending it with those types of people.
