Re: Jane’s Exercises IIIwell logically it is understood ... .... I love Maths and Music ... dunno which more #28 20090401 20:48:51
Re: Jane’s Exercises IIINo, it is not. Would you like to attempt #9(ii) again? #29 20090401 20:59:10

Re: Jane’s Exercises IIINo, still wrong. Also you still have not proved #1 satisfactorily. Last edited by JaneFairfax (20090404 20:42:42) #31 20090403 06:57:52#32 20090403 20:17:27
Re: Jane’s Exercises IIIhahahaha ... u really know just one way to prove a prob and think that it is the only way ... let me tell u dear ... there are more than 5 ways to solve any problem in math I love Maths and Music ... dunno which more #33 20090403 20:20:07
Re: Jane’s Exercises III@jane ... prove me 1+1=2 I love Maths and Music ... dunno which more #34 20090403 20:45:47
Re: Jane’s Exercises IIIOf course there many ways to solve a problem. That does not mean that any old way to solve it is correct. Some of your solutions are correct, some are not. #35 20090404 11:57:46
Re: Jane’s Exercises IIII thought I should give the solution to #7 because that problem has to do with algebraic topoolgy – but I can’t expect every MathsIsFun browser to be familiar with algebraic topology, fascinating though the subject is. #36 20090404 16:47:58
Re: Jane’s Exercises III@jane ... if my solution is wrong i will accept that before even u can tell me about it .... but if i am right ... u need to accept it ... there are no old ways in math .... u only accept some new ways if u think it is better than the previous one .... but in no way i can find your solution way better than mine ... both of us used contradiction to solve it ... so how can mine be old ... infact u used the old way of squaring both sides etc. the one we used to do in schools ....

Re: Jane’s Exercises III
That is where your solution to #9(ii) wrong. Your solution to #1 has a flaw as well. But I will leave you to spot it yourself as an exercise. Last edited by JaneFairfax (20090404 20:43:02) #38 20090404 20:04:40
Re: Jane’s Exercises IIIhmm agreed nice spotting .... thanx.... [] I love Maths and Music ... dunno which more #39 20090411 05:28:23#40 20090414 23:46:05

Re: Jane’s Exercises IIIBy the way, what do people think of my exercise questions? (I set all of them myself.) Are they too difficult? Or too easy? #45 20090505 21:10:34
Re: Jane’s Exercises IIINB: A pgroup is a group in which every element has order a power of the fixed prime p (including the identity, which has order p^{0}). It is worth noting that such a group need not be finite – there do exist infinite groups in which every element has finite order. #46 20090507 05:17:34#47 20090513 19:42:16#48 20090523 08:36:20
