Yesterday I've noticed some relationships with cosine and square root. Anything interesting about it? I was trying to find the smallest width on an hexagon with radius 1.0 and I noticed that I could get it both by √3 and the or two times the cosine of 30∘.
I wondered if there would be more matches and so I notice these even though might look silly... 2×cos90∘=√0 2×cos60∘=√1 2×cos45∘=√2 2×cos30∘=√3 2×cos0∘=√4 Is there anything interesting to know about these? Thanks
