  1. Hey I took bm hl and Eco hl in my IB.. I think Eco will be more useful!! It will make ur base Stronger and sharper! Evn if u do Eco later this base will help u make things clearer! From my experience the more u study Eco the more u understand it!! And with bm it's like if u learn once it's there staring at u!!! So I would go for Eco! Bt if u take both of them it's nothing better!! Hey I took bm hl and Eco hl in my IB.. I think Eco will be more useful!! It will make ur base Stronger and sharper!

  2. granted.. But you cannot do well in ur finals! ( BUT DO VERY WELL.. I CANT CURSE ANYONE) i wish there was no hatred in the world!
  3. banned for being above me to be banned!!
  4. yes i think it is valid!! its is a good one indeed!!
  5. i can't remember the question at all... what was it???
  6. yes it is!! i got the angles like 71.42 something and 288... but not sure about the 288 angle because when i tried re-substituting it i got the answer in -5m^2 but anyways area can't be negative and also if we try to imagine the kind of window it makes its weird!! so not sure about 288 at all... but hope 71.42 is correct!!
  7. yeah.... correct!!
  8. yeah this question....the point you misses out is that the question in a) was to find P(X>27) and we get 0.2 (because 0.5-0.3) obviously!!! so in part b) we had to find the standard deviation and the way i think i did is right!! P(X>27)=0.2 P(X<27)= 1-0.2 =0.8 (so see you need not have a negative sign) then you have P(Z<27-25/sigma)=0.8 so you take the value from the inverse table for 0.8 (which is positive) and solve for sigma and the answer i got was something like 2.38... i dont remember the exact figure... and yes tell in which equation you substituted? may be that is also anot
  9. hey guys... how was the paper2 TZ2...??? i think it was very calculative (obviously... it was a calculator paper haha ) but i thought the last question especially the last part c or d may be was very confusing.... they asked that john wants windows of same area (A) but different angles. so find all the possible vales of A. confusion no.1- which angle were they taking about?? whether he wants different angles in 1 window itself and such two windows OR two windows with different angles from each other but each of them having the same base angle... (i hope i am clear with my question ) confu
  10. hmmm..... right!! but then the there should also exist the horizontal translation in the equation, shouldn't it?? because even if you reflect it then too the does not exactly start from the origin like sin....
  11. yes absolutely correct bud!!!! actually that guiding question was like a big big hint to the interpretive meaning of the poem.... i doubt if i might have attempted the poem if that guiding question was missing.... anyways thanks to whoever set that!!!!
  12. okkie..... i am not sure whether i did A=(-50)..... i did A=50 i guess.... but why will there be a minus sign???
  13. Soo true... I dropped to Maths SL in IB1 and after seeing their faces coming out of that examination hall I'm super glad for it... What did you get for the questions? The ones I remember; Logarithmic questions, I put down A = 5 (since 3 ln x= ln x^3 and ln x^3 + ln 5 = ln 5x^3). I thought it was a shift by vector (0, ln 5) but wasn't completely sure about that one... In quotient rule I got 6. In the last question h(21) was like 2.41 or something, and the expression if I recall correctly -50 cos ((pi/10)*x)+50. (Not looking forwards to hearing that all of this is incorrect... haha ) yes i too
  14. i hope we can start the discussion of the math paper1 now since its past 24hrs..... so on an overall note how was the paper guys???? i thought it was quite simple so expecting a tighter great boundary!! anyone with similar or different thoughts??
