I just watched that movie called Old School (yes it’s from 2003). They had a nice math question during the movie. It was as follows:
Which of the following is a generally accepted graphical technique for determining first order system parameters?
a) Harriot’s method of solving cubics
b) Pythagorean triplets
c) The migration method of graphing quadratic functions?
You can see the clip over at Oliver Knill’s site: mathematics in movies.
