#9(i)


For (ii), there are still gaps.

No, it is not. Would you like to attempt #9(ii) again?

No, still wrong.

hahahaha ... 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

Of 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.

For example, your solution to #6 is correct, even though it is different from mine. My solution uses the AM–GM inequality.

If your solution is correct, then congratulations. If it isn’t, and I point out that your solution is wrong, then you should go back and check your working instead of being stubborn about it.

@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 ....

so in my books ur style of solution is in no way nearly as interesting or nearly as appealing as mine ...


oh yes ... as u say my solution is wrong ....

tell me one step which is wrong ....

if u can't show one such step ... never again say someone wrong
