0 Guest Posted October 28, 2011 Report Share Posted October 28, 2011 (edited) Sorry to nitpick, but the wording is a bit confusing (unless that's intentionally part of the trick to this). It could just read "what is the minimum possible value of x2 + y2"... the fact that you're looking for a sum is a given. Again, unless that's part of the trick.

0 voider Posted November 3, 2011 Report Share Posted November 3, 2011 (edited) x^2 + y^2 = 4 at (-sqrt(2 + sqrt(2)), -sqrt(2 - sqrt(2))) = (-1.84776,-0.765367) (-sqrt(2 - sqrt(2)), sqrt(2 + sqrt(2))) = (-0.765367, 1.84776) (sqrt(2 - sqrt(2)), -sqrt(2 + sqrt(2))) = (0.765367, -1.84776) (sqrt(2 + sqrt(2)), sqrt(2 - sqrt(2))) = (1.84776, 0.765367) Edited November 3, 2011 by plainglazed Quote Link to comment Share on other sites More sharing options...
