I agree with this 100%. Hard math rarely has a use outside of it's scope. How often are you really trying to simplify the cotangent multiplied by an arcsin? Sure people who deal with trigonometry do often. But that subset of people is even smaller than people who do geometry. I'd wager carpenters do more math on a daily basis than the average programmer.
