fuck engineering schools

>evaluating the integrals with riemann sums instead of memorizing the integral formulas
if you didn't write the integral formulas on the exam, that means you didn't write your answers in closed form, so you don't get any points for just restating the fucking problem, you brainlet

So, you failed to solve the problem as stated, got no points for it, and are now complaining about it?

Drop out from engineering and go be a physishit, OP.

freshmen shouldnt be able to claim they're in an "engineering school". Nothing even vaguely engineering related gets taught till junior year, and nothing useful till you're in senior tech electives. The first couple years are just there to develop the math skills necessary to even begin to solve/comprehend 300-400 level course material.

No, he docked points because you used an outdated method of integration that can't even measure most functions. Dr. Lebesgue would like to have a word with you after class.
