aldld Posted June 30, 2012 Report Share Posted June 30, 2012 For part a, you can eliminate the p and q on the left hand side by applying the group's binary operation with and .By the definition of a group, , the identity, so they cancel each other out.Do the same thing with q:For part b, look at the second equation. We know that , so given that , this means that .So the first equation can be written asSince they cancel out and we haveAnd just as before, we can get rid of the q from the right hand side to isolate x.If you have any further questions, let me know. I'd be happy to help! 1 Reply Link to post Share on other sites More sharing options...

aldld Posted June 30, 2012 Report Share Posted June 30, 2012 (edited) Thanks, that was really helpful. I didn't know you could just leave it like that.No problem At least I hope it's okay (since we haven't covered option material yet and this is only based on my own self-study) Edited June 30, 2012 by aldld Reply Link to post Share on other sites More sharing options...
avilezj Posted July 1, 2012 Author Report Share Posted July 1, 2012 Are you doing the FM syllabus? Reply Link to post Share on other sites More sharing options...
aldld Posted July 1, 2012 Report Share Posted July 1, 2012 (edited) Are you doing the FM syllabus?No, just HL. Further math is not offered at my school unfortunately So instead I plan on self-studying the material in my spare time.
