I thought that also couldn't be concluded. Got the right answer anyway so doesn't matter I guess.

Section 2 was extremely hard. Couldn't do about 7 Q's in the end since the passages were difficult and long.

I did the same thing. Edit: Wow... Sure a lot of ppl did the UMAT... 1711 views already!

+1 That's exactly what happened to me... Took too long to read and ended up not doing the last 7 questions coz I didn't have time in section 2. I'm expecting the most horrible mark ever in that section.

Just simultaneously solve OQ with the ellipse and find the intersection in the 4th quadrant.

Section 1: unexpectedly easy Section 2: Epic Fail (guessed 7 questions due to time constraints+the questions were way harder than what I saw in medentry) Section 3: Easy to alright

Thanks, it helps, but exactly how is phonon absorbed by the 2nd electron?

LOL 19/36 gave me 54th percentile

lol.. That's quite an unsatisfactory explanation though.. Thanks anyways

Then what happens to the phonon?

I know that phonons are quanta of vibrational energy, but what role does it play in the BCS theory? I have seen Jacaranda Physics going on about exchange of phonons between electrons but I don't really get it. Can someone explain me the role of phonon in BCS theory in a way that will be...

how does adding mass decrease air resistance? It might decrease the impact of air resistance on pendulum motion though.

expand the numerator (9+6sqrt x+x)/20x dx =(9/20x+3/(10sqrt x)+1/20) dx integrate it 9/20ln abs(x) +(3 sqrt x)/5+x/20+C

$Assuming that you can prove the hint,$ \\$let M=3, N=1.$ \\sin3xsinx=2cos2x+1 \\sin3xsinx-2cos2x-1=0 \\0.5(cos2x-cos4x)-2cos2x-1=0$ using the hint$ \\0.5(cos2x-(cos^22x-sin^22x)-4cos2x-2)=0 \\0.5((-2cos^22x+cos2x+1)-4cos2x-2)=0 \\-0.5(2cos^22x+3cos2x+1)=0 \\-0.5(2cos2x+1)(cos2x+1)=0 \\ \\Thus...

Just keep in touch with them Still living on the same Earth!

Well, there are years of tertiary education to go.

square both sides 5+x+x+2sqrt(x^2+5x)=25 sqrt(x^2+5x)=10-x x^2+5x=100+x^2-20x 25x=100 x=4

No, I was asking a simple question like are you sure the question says a/b^-1, which is just ab anyway? coz it's a strange way of writing and it has to be a/b, not a/b^-1 looking at the answer I.e. what drongoski is asking

Sure that u got the highlighted part right? Coz the whole expression then = Int (cosxsinx)(2-sin^(2)x)^0.5 dx
