How did Maths 12 go? No discussion

[Ram97]

Values for tan theta were tan-1(2) and tan-1(3)

 

[Ram97]

How many marks were there for the area Q's.

Was the variable question,u=6?Did we have any double differentiation questions?I can't recall doing it.I hope i didn't miss anything.

No. there was no double differentiation, don't worry

 

[farhan141]

Any one remember the equations of line and curve where we had to find C? Also what was the tanTheta question part 2? Not ANSWER

 

[Ram97]

Sinx - cosx/sinx + cosx = tanx/6

 

[DaniyalK]

Tan theta was 2 and 3... I put the values of theta in the original equation and the equation was satisfied

for the time question
I gave the answer as 10<t<20 T_T
why why why why 'I misunderstood the question

when i pluged in t=10 i got my answer as 90, thats why i gave my answer as inequality like yours, i said h>90 then solved for what t equals to. not sure though.

To find the coordinates of C i found the midpoint of AB and the gradient of AB. i used m1*m2=-1 to find the gradient of the perpendicular bisector, i used the coordinates of the midpoint AB to form an equation, then used the fact that a line is parallel to AB, so they share the same gradient but used here the coordinates (3,1), solved them simultaneously but comparing my answer to you guys, mine is incorrect, how many marks will i loose?

I have totally lost 12 for now.. Hope not more..

 

[AbdullahBShakeel]

I differentiated the variably u wrong so i got my stationary value as -144 lol

 

[SonamKhan]

Anyone remember the range for the functions question?

 

[pakhee]

Anyone remember the range for the functions question?

wan't it f(x)>3/2?Anyone remember the value of u?I got 6.

 

[Ram97]

Value of u was 6
What was the value of k in functions?

 

[Ram97]

Heard that the paper was leaked. Is this true?

 

[BhaiArshad]

Heard that the paper was leaked. Is this true?

Yes.

 

[Kruthi]

Heard that the paper was leaked. Is this true?

Really? Where did it leak? How?

 

[BhaiArshad]

Really? Where did it leak? How?

Lahore. Don't know how.

 

[Kruthi]

Lahore. Don't know how.

Isn't that unfair? The cheaters could end up being the world toppers! this is so bad!

 

[pakhee]

Value of u was 6
What was the value of k in functions?

k would be 3/2.

 

[DeadlYxDemon]

Lahore. Don't know how.

How? Because of them the threshold could be high!
