“Quod erat demonstrandum”: “that which was to be demonstrated”
Does anyone know the Latin for “that which will be demonstrated”?
I am grateful for your consideration in this.
~Libre
Quod erit demonstrandum.
One letter ~ I love it!! Thanks so much, Quartz.
Technically “demonstrandum” means “that which is properly demonstrated” – the gerundive being one of propriety, appropriateness. So it could either be “Quod erit demonstrandum”, with the implication that the demonstration-to-come is proper and appropriate, or “…demonstratum”, which simply means “that which will be demonstrated”, with no implication of appropriateness or propriety. The first might be right to introduce a proof in response to someone’s expectations, the latter if someone is merely announcing what he intends to prove on his own volition.
