ok re...

yaar, ur drawing is wrong, ill show u the right 1.

in my diagram, the 4 sections show north East(+,+) , North West(-,+) , South East(+,-) , South West(-,-).

as the question says the wind appears to be blowing from north east, means that the wind is coming from (+,+) 'B'.   stress on this line again

and at the same time the boy is traveling south at 'A'.

centre = 0

now the relative velocity of '0A' and 'BA' = 'B0' therefore the the angle B0A is 1350 and angle 0AB is not..

tu hi soch, itna chota angle in ur drawin, how can it be 1350

i hope this was clear.

guys...if any candidate giving exam in 2009 oct/nov session.....please be aware of the fact that there is 100% probability that this relative velocity question will come.....and more over its the relative velocity river question....take care...n best of luck 4 the upcoming 0 "zero" level exam hat will partly help us to shape our future studies....... ;D

in dat case...please check the pattern of hw questionz come....u wl find dat alwayz dey r da same...if may/june session vector velocity comes.....den in oct/nov session relative velocity comes....n vice versa.....seeing da pattern of da last few years......nw dey r giving more river velocity questionz...n hence ma deduction..... 8) 8)

yes, that would be very helpful. Till yesterday i didn't know that Loga(b) could be written as 1/(Logb(a))

i knew it yesterday when referring your website, very helpful.

Du u take tuitions for students after IB...

OK, since our Additional Maths exams are next week so I bring up this topic again for Add Maths students in need of help ;)

So if you are stuck with anything, post your doubts here and Add Maths students will help as soon as they can.

Good luck to all of us :D
