How do maths and PE relate?

Answer 1

The awarding of a PE registration requires some number of years' experience in the

practice of Engineering, plus the successful completion of a written examination in

the principles of an Engineering specialty and in the principles of Engineering Economics.

All I can say by way of such a relationship is that it's highly unlikely that one could

satisfy that body of requirements without a significant familiarity with a good deal

of mathematics. That was certainly true on the way to my PE at least.

Oh my. If you're talking about PE like in the gym, then forget anything I said.
