I bow to you sir.

I'm guessing point T: (0.5, 0) and the area is 0.75 units squared. How wrong am I?

So neither Fraggr

Ah. lol I didn't look at your location.

I can't think how to approach that question

area of rect = (1 - t^2) * 2t
d(area of rect)/dt = 2t - 6t^2

Maximal when d(area of rect)/dt = 0
t = +/- 1/sqrt(3)
(ignore negative solution)

So area is (1 - 1/3) * 2/sqrt(3)
= 0.770 (3sf)
