hey do u think my answers are correct ? ive mentioned them above
Well I have some of the same answers.1,2,3,4,5,8,9,10,12,13.I don't remember What I wrote for the rest,Didn't do that g(x) transformed graph and will only get method marks for integration(One of the area 'bits' I got was negative and I decided to focus more on the other questions yielding more marks than figuring out why it was negative)
MY ANSWERS 1. p=1.5, q=63 2. a. 14.556, b. 7.278 , 30.556 3. a. x< or equal to 4.5 b. x> 1.5 or x< -5 and 1.5<X<4.5 4.arithmetic series quest a)4 b)400 c)didnot solve 5 the surd question a) k=32 b) 5 sqrt 2 c) n=50 6. log question sim. eq. x=0.5 y=8 7.centre(x-a)^2 + y2= a^2A= 25/8 = 3.125 8. angle sin 19.5 and -30 9. geometric series n= 39 10. graph x coordinates A= 8/5 B=20/9 and in the transformed graph we had to multiply y values with 3/2 11. Q(x)a= -10 b= 13 12. sectorarea = 0.654 13. some angle question pi/12 and 5pi/12 13. integration 0.33 (i know this is not exact as asked in the question)
Pi by 12 is out of range range from pi by 4>theeta plus pi by 4>2pi plus thita
range was from -90 to 90.. 30 is wrong because the negative sign only tells you in which quadrant sin is negative.. so final answer was 19.5 and 330 ( sin is negative in the cos quadrant with respect to the range).. 330 because you subtract 360 and 30 ( which is in the cos quadrant where sin is negative) and 19.5 because sin-1 of ( 1/3) is only positive in the first quadrant

i am sorry but you are wrong... the correct answer is -30 and 19.5. 330 lies beyond the given range

I cant remember what I wrote exactly but -30 is wrong since the negative sign is supposed to guide you.. so it should have actually been 30 and not -30 ( I confirmed with my classmates as well)

30 is fine but -19.5 is not ( its supposed to be 19.5 ) cause it was sin-1 of (1/3) which 19.5.. you'll probably score 2/4 marks which is fair enough provided you had shown your steps:-)

I wrote 30 but I got -30. I did that because when I was going through the paper I remember my teacher telling us that u don't write the sign because it just helps us guide.

Yeah that's why I'm telling these other guys that its 30 and not -30 you're right

she only meant that when trying to find out the sin value but that doesnt mean u dont use the negative region; which is supposed to give -30
I'm pretty sure the range was -180 to 180 and when the range includes negatives, you go in the clockwise direction as well and you take it angles as negatives

the range was -90 to 90, but ya what ur saying is right..

I got -30 and 19.5. I do think the sign is important as it indicates whether the angle is clockwise or anti-clockwise. I tried putting -19.5 and 30 into the calculator but they give sin with negative value.
