I tried to help some dude understand integration by parts, which I’m not sure I’d understood myself. I warned him. But it was late, he was desperate, and I was just going to go play computer games anyway.
I figured it out, but I’ve no idea if I got him sorted out for his final.
The professor is interrupted in the middle of his lecture by a student who asks about one of the previous week's problems:
— Could you please work an example for us?
— No problem!
The professor writes a problem statement, then scratches his head, tugs on his collar, rubs his chin, and at last scribbles a complicated integral on the board.
— There you go!
— Excuse me, professor, but could you please be a little more explicit?
— What do you want from me? I just did the problem 3 different ways.
Only getting 2 ways to solve it brings us back to russian jokes:
A soviet maths prof finds out he'd make more money as a labourer in the shipyards, so after more than a few carefully-distributed bottles of vodka he manages to change profession. A month or two working in the yards, and he sees a notice on the bulletin board offering a bonus to workers who sign up for a special "maths for the proletariat" evening school course.
Figuring it's easy money, he signs up, brings a novel, and sits in the back of the class reading instead paying attention. Then the prof calls him up to the brownboard, and asks him for the circumference of a circle.
Suddenly, our ex-prof blanks. Frantically he scribbles and scribbles on the brownboard, only to wind up with ... -2πr. No, that can't be right, but what went wrong?
Just when he's about to crack trying to figure out his error, he hears a friendly voice from one of the front-row students:
A joke in Russian universities:
- A teaching assistant tells a student: "Look, I've been explaining it to you for so long, that I myself understood it!"
