Dunno what the Wikipedia writer was on, er, referring to, but I have a Masters in psychology and am in the midst of the doctorate program and have yet to have had a use for any trig (which is good, because I didn’t know it in high school, and don’t know it now). Statistics yes, but not trig.
That’s a fair point. I don’t think that trigonometry is necessary for EVERY aspect of those fields, but it COULD be used in those fields (and, in at least some cases, may well be required).
