How was Additional Mathematics Paper 4037/12

[Dark Destination]

since it was in factorised form the turning point cud be fig by adding x coordinates and div by 2) and later process carry on...was it abs necessary to use discrimanant

Idk, i calculated the turning point. Is that fine?

 

[Dark Destination]

nope 270 was not in either coz both had single variable with range 0<x<180

So are you saying we had to reject one of the angles? There was such a situation? :/ I didn't get any such situation

how did u tht is the question?if by differentiation then correct i used factorised form for easy calculation

 

[M.Omar]

looking at range 270 degrees cud not be asnwer in first place and I did get tht situation

-b/2a

Did you get 270 in the first question, and you rejected it?

 

[M.Omar]

Did you get 270 in the first question, and you rejected it?

i dont quite remember but i do know whenever it did come it was to be rej may it be in 1st or 2nd part.....as range ...

U r a pretty big liar Nabeel hope u can relate

I am sure the range for the second part was 0 - 360

First one was 0 - 180

But was 270 in first or second :/ ?

0,101.3,180 for first not 0 and 180 only!
no 270 did not come in first and for second it wud be rej....thus

 

[Dark Destination]

0,101.3,180 for first not 0 and 180 only!
no 270 did not come in first and for second it wud be rej....thus

Range for second part was till 360

harder a bit due to relative velocity. cuz i suck at it !! the combination ques was tricky though. Mostly permutation(digits) ques are harder and tricky but i didn't know about this case with the combination ones.

So the paper was harder than previous ones? Or easier?

0,101.3,180 for first not 0 and 180 only!

101.3? :/

 

[M.Omar]

?

A long time ago...when u solved a riddle which was 18
1118
3118
132118
sth like tht....u said u were normal category student in maths and all tht and u r now like...wow!
remember much?If u r Nabeel.Ahmad

 

[sid2333]

and what was the ans for the third part of this ques? the radian one for 0<z<pie??

0,101.3,180 for first not 0 and 180 only!
no 270 did not come in first and for second it wud be rej....thus

 

[M.Omar]

Range for second part was till 360

no i am sure to 180

Yeah

 

[Dark Destination]

no i am sure to 180

I did not get any rejection case of 270. Are you absolutely sure that was there?
Where? In the first part or second one?

 

[Dark Destination]

What were the trignometry questions? Does anyone remember the questions?

For me the answer for first question was 30 150 :/
