WebThe kissing number k(3) is the maximal number of equal size nonover-lapping spheres in three dimensions that can touch another sphere of the same size. This number was the subject of a famous discussion between Isaac Newton and David Gregory in 1694. The first proof that k(3) = 12 was given by Schu¨tte and van der Waerden only in 1953. In ... WebFeb 21, 2024 · If cosθ = 3/5, then evaluate . Solution: Given: cosθ = 3/5. From Pythagoras theorem, AC 2 = BC 2 + AB 2. 5 2 = 3 2 + AB 2. AB 2 = 25 − 9 = 16. AB = 4.
