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
