At some point one of these imbeciles was blabbing about artillery calculations and in the course of "solving" an equation he came to the conclusion that
cos(x) = 2.37or some such. One of the math. department's students raised his hand and expressed his concern
"Comrade major, we - at math. department - actually learned that
-1 <= cos(x) <= 1Are you sure that your calculations are correct?"
Dumb-ass major (perhaps it was a dumb-ass Lt.-Colonel) looked back, paused for a moment and said "In the time of war cos(x) was reaching 4, but rarely..."
