Jack Price wrote that during the 1970s:
"As educators we did not show students real-life applications of mathematics and therefore did not answer the question on many students' minds, `When will I ever use this stuff?'"
I cannot say with certainty what Mr. Price had in mind but I suspect we would all agree that by "real-life applications of mathematics," it is likely that he meant applications which are routine and essentially necessary in solving problems a significant percentage of the students could reasonably be expected to encounter at some future date.

I'm not so sure that it's all that "practical" but in any case, the way it's usually done makes no real use of trigonometry.

Can you name a place where it's done? (Contrary to a common myth, it is _not_ done in navigation.)

This may be so but first I would like to see a few examples of "real- life applications of mathematics" as outlined above which a student could understand at the time he was taking the course to which the example relates.

Not just daring. Plain stupid.

I agree but does Jack Price?
