My middle-school-aged daughter asked me this year if I had ever used trigonometry in real life. I do math everyday for my job, but I had to answer to her that I hadn't really ever used trigonometry in anything I do.

Fast forward a few days. . . my wife was trying to figure out how to comply with six foot social distancing requirements at a church function. The question was "how many people can fit around a round table and still follow the rules." Lo and behold, trigonometry and geometry proved helpful in this situation. And I haven't used them since.

So for me, only in the case of a (hopefully) once in a lifetime pandemic.
