How did Maths 12 go? No discussion

[asadalam]

in the very first question was c=8?

Yup

 

[farhan141]

Values of c were 2.5 and -3.5 .I got that tan theta one wrong im sure as my ans were for tan=-1 and 6 somehow so i got 80.5 and 135.Im sure those are wrong though.Did you manage to prove that trig identity?

Yes c is correct. I turned the left hand side into sin and cos. Sir told us u can choose either side.

Also, I want to know the tanTheta question. I remember tanTheta - 1/tanTheta + 1 only

Can u tell me two values of c in 2nd part of integration question? Also does anyone remember the tanTheta question?

tan theta was 71.56 and 108.4.

Really?I got tantheta as +3 and -3.

 

[farhan141]

I'm asking abt the question *facepalm*

 

[pakhee]

Yup

Hey,what did you get for volume of revolution?

Hey,what did you get for volume of revolution?

16pi/3

Can we all agree it was kinda harder than previous years? And that wheel question i lost the whole 6 marks, ive never seen anything like it before and about the sum of the series did anyone get a negative answer? One of my answers was negative -1991 is it wrong?

Anyone remember the tan Theta question?

sin + cos / sin - cos = tan +1 / tan -1

 

[farhan141]

sin + cos / sin - cos = tan +1 / tan -1

2nd part

Same here, I was gonna do wheel one in the end but I didn't have time then and I didn't rly know it either..

Any guesses on the thresholds?

 

[yoyo00xx]

it will be high because paper was easy

[farhan141]

60-62 is my expectation

it will be high because paper was easy

 

[AbdullahBShakeel]

My teacher said 61 would be A.. And 2 to 3 questions were pretty badass..

 

[farhan141]

I lost 6 marks in wheels. 6 in functions question.

 

[AbdullahBShakeel]

I got that 3rd part of the wheel wrong so 3 marks, 1 in vectors, 1 in that prove identity, and 5 in that variable u and also got that sum to infinity wrong :|

 

[farhan141]

How did u lose in identity, u and sum..

 

[pakhee]

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.
