cmon someone answer me im comtemplating of going to www.save.org

wtf..... hey how come you dont restrict the ellipse?

isnt it jst tha top bit? not  the bottom because t is greater than zero

also with tcostheta and tsintheta can you do it straight away n obtain tantheta straight away?

Which ellipse

Tan(theta) is found in the question succeeding that, they required you to state two equations so that T and theta could be evaluated.

Question 4?

It's made up of trig functions.  As time goes on, the pattern repeats.

Hence, it's a full ellipse.

I got E for MC 12.. Anyone else? maybe just me? but its a definite integral.. and the area is clearly positive.. so E??

same..  haha

[Rayle]

With Q12, f(x) is the quadratic and the cubic is the anti-derivative. Hence when you're evaluating the integral, the area is actually negative.

did anyone think of using the segment formula we learnt last year for the area in the last Question?

Yes, but i couldn't remember it.

is it possible if neoen posts the solutions to mc?..as in worked solutions ..i dun rememeber any of the mutiple choice questions?!!

Cool, nice MC answers, I got the same *thumbs up*

That's encouraging I got at least 3 wrong, though.

WHAT???!!! which ones?

I changed them from my answers to the correct ones in the OP, so you're looking at the correct answers.

In any case, the ones I got wrong were 2,7,12 - all careless...

alrite guys what would g1 c+, g2 b+ and g3 C get me in spec raw, and then standardised,,,, --- these r following 2007's distribution?

[azn_kiwi91]

I used the segment formula for the last question.

For those wondering:

1/2 r^2 (theta - sin theta), theta in our shaded circle was 2pi.

PS: btw, what do you guys use to input those mathematical symbols.
