Exit here to skip rambling examples. I once took a page full of integrals of trig and polynomials to at least five math majors where I was working at the time, to check my work. ALL of them said they had forgotten how to do that long ago (except one, who never got around to actually checking it. So I said, what the hey, and put it into the code, and it worked. After it had been returning apparently correct answers for several weeks, someone complained that there was a subtraction where there should have been an addition in the original. This was first year calculus--which my BSCS from "Degrees R Us" did not include. I just looked up two items in a table of integrals, and used my high school algebra to derive the rest. (I also had two senior domain engineers tell me before I started that it was impossible to calculate the values I was trying to get.)
