clinton1225 Posted January 25, 2013 Report Share Posted January 25, 2013 I've replied to your message.and please don't post answers in the forum.Hi I saw you were helping others, I was wondering how I use the technolohy to investigate other values of r and OP. I am using geogebra, but don't know what to do,i cant seem to get the circles to intersect correctly when r is greater then OP. I cant find the general statement for OP'. PLEASE help me, even though its a year later... Reply Link to post Share on other sites More sharing options...

smiley2013 Posted February 20, 2013 Report Share Posted February 20, 2013 I've been working on this IA for around 5 days now, and I have the two general formulas from step 1 and 2, but how do you justify why the overall conjecture is true? It says it my be useful to add line segments to prove validity of the formula but how?I know you use trig with sine and cosine rules- thats how I got the formulas but I don't understand what the underlying reason for the relationship is.Please Help !!!

candy6 Posted February 27, 2013 Report Share Posted February 27, 2013 Any tips to avoid repetition with the calculations? Reply Link to post Share on other sites More sharing options...
dgmanchia Posted March 29, 2013 Report Share Posted March 29, 2013 (edited) I found OP' values when OP is held as a constant y r values are modified, but I cannot figure out the pattern! Does somebody want give me a hint please? I'd be soo thankful Edited March 29, 2013 by dgmanchia Reply Link to post Share on other sites More sharing options...

Do I change classes? Do I dropout Sophmore year?You've got ages till you decide on whether you want to take IB or not. As you get older, it's easier to understand the information given. You should talk to your teachers if you don't know what to do. If you are willing to put in the effort then I'm sure you will do absolutely fine.
