minus-square@TootSweet@lemmy.worldlinkfedilinkEnglish16•edit-221 days agoThis isn’t intuitive to people? 2/sqrt(2) = ( sqrt(2)*sqrt(2) ) / sqrt(2) Then cancelling out one of the sqrt(2)s in the numerator with the sqrt(2) in the denominator, you’re left with sqrt(2). I do a lot of toodling around in OpenSCAD, though, and sqrt(2) tends to come up a lot because, you know, Pythagoras and right triangles and all that.
