Get used to it. All functions are infinitely often differentiable, even if they aren't, all arithmetic operations like division by zero can be performed, even if they can't, all DEs have smooth solutions, even if they don't.

wow, someone is samefagging bigtime in this thread.

someone also failed their physics course pretty hard. how's that sore feeling OP? how is it to feel intellectually inferior?

So you're that faggot in class who likes to hear his own voice to the extent that he stops the professor from getting to his point by indicating where he is hand-waiving for the sake of brevity and conciseness?

Fucking insecure spergs, go back to your online forums and leave us students to our sex and drugs. If you don't understand degrees of abstraction, you have no basis on which to instruct a professor, and should bring up your concerns on your own time, not on ours. Goddamn.

One of the most hilarious things is what while math is useless without science (or some other form of application such as economics or business), science is far from useless without math. HAHA!
