I was dabbling with DEFINING NEW TRIG FUNCTIONS recently, and I tell you that coming up with zinger functions IS NOT EASY!!!

My favorite semi-obscure mathematics terms are 'subtrahend' and 'minuend'. I think everyone from my generation learned them in grade school in the USA but most promptly forgot them since they were never used again. I always thought that they would make excellent names for a pair of small dogs.

I filled entire pages of subtrahend and minuend in my firsts grades, just to memorize those terms. Damn teacher. Edited: 15 Sept 2013, 4:34 p.m. after one or more responses were posted ▼ Gerson W. Barbosa Posting Freak Posts: 2,761 Threads: 100 Joined: Jul 2005 09-15-2013, 10:59 AM Here (in Brazil) we call them minuendo and subtraendo. I've just correctly guessed what the latter should be in Italian: sottraendo. This makes for a nice mnemonic. From Wikipedia: -------------------------------- Per fare una sottrazione in colonna bisogna prima scrivere il minuendo, e sotto, il sottraendo: 86 - 34 = 52 ```86- 34= -- 52 ``` -------------------------------- These were taught in first or second grade, I think. Good old days when memory was always fresh and neurons worked at full speed :-) ▼ Massimo Gnerucci (Italy) Posting Freak Posts: 882 Threads: 23 Joined: Jan 2005 09-15-2013, 12:19 PM Well done Gerson, A+ or, as we were used here, 10+ :) ▼ Gerson W.

Fred Lusk Member Posts: 168 Threads: 10 Joined: Jul 2007 09-16-2013, 02:53 PM Some of those "new" trig functions were used by surveyors in the pre-computer days and may still be used by them from time to time. I was introduced to them when I took Surveying I & II in college. But, since I'm a civil engineer and I have a computer, I have no need for them any more.
