In the Good Will Hunting movie there is a quote of a professor towards his students while writing a math problem on the blackboard:

"So please finish Percival for next time. "

You can watch it here:

I've searched it already. But the question is. Why should a math problem resemble a knight of the Round Table in the King Arthur legend? What's the background of this?

What's the meaning of the word Percival?

  • The knight of the Round Table is just a famous person with the name Percival. Anyone can have the name, though. Is it possible that the professor is referring to a person?

What was heard was Parseval, although it is often transcribed wrongly. Marc-Antoine Parseval des Chênes (1755 – 1836) was a French mathematician whose work preceded Fourier's (the class topic involves Fourier analysis).

Parseval's Theorem is often used to demonstrate mathematics software, including Maple:
