 Sulo_Seppa But really, how do I implement the sqrt function? KD19 To prove a general case, you need to be able to prove EVERY special caseso if you prove a few special cases, you might see a patternI dunnoso I'm trying to understand 2d space first nitrofour the radio sis half of the distsance between the distance found between the radius of the two pointsthat's very important to remember Sulo_Seppa anyone know? sqrt? KD19 and to understand 2d, it's still to general nitrofour remember what i said. KD19 so I try to understand nitrofour it answers everyone's questionthe radio sis half of the distsance between the distance found between the radius of the two points lokie Sulo do u mean implement it as in programming/? KD19 special cases Sulo_Seppa lokie: in general, but I am a programmer KD19 sulo google "square root algorithm" ed KD19- I think I am about to give up for the night KD19 ed yeah I have a light headache ed my brain is off and it's not fair to have you do all the thinking in this when its my problemare you here often? KD19 I will be from now onbut I can't talk hereunless I'm voiced ed Why not? nitrofour do i have to repeat myselfi hope noti answered the question thoroughly lokie Sulo here is somthing, http://mitpress.mit.edu/sicp/chapter1/node9.html not sure how much help KD19 ahto prevent abuse ; ) Olathe Sulo_Seppa: An easy, but probably inefficient, way is to do each bit from high to low. If setting it to 1 is too high after squaring, set it to 0. ed KD19, well whatever ;) thanks so much for your help KD19 hmnpanyway, my lemma wasthe problem we were working on is how to prove that you can't intersect the two outer pointswithout also intersecting the middle pointright? ed yes i think we agree on this one
