That's 'cos while lots of us took it, we don't hang out together much. (cough)
Oddly, geometry & trigonometry is one of the things I learned in high school that I still use to this day. It comes up in all kinds of software engineering that has no obvious connection to graphs, plots, GIS, or anything like that.
