You then have to multiply by two as when rotating through 2pi radians you multiply by pi, V= pi x integral hence V= angle/2 x integral, so it’s 40/9
(Original post by RVSZN)
The equation was y=2x^1/2 + x^-2/3, when you apply this to the volumes of revolution equation with the limits x=1/8 and x=8 you get something like 103.725, which then to find theta you do (461/2)/103.725 and you get 20/9

Yeah I got 4.4 radians but put it in degrees first lmao

5 marker. It was the first "proper" question, I think. Asked you to find the volume of revolution for the region bounded by the hyperbola, y-axis, x-axis and the line y=a.
yeah that was a show question that the volume was ma^3 where m was 3.40 (3.s.f) m=13/12(pi) not sure how people were getting 2.2 radians

I had literally no idea how to do it, so I don't know what the correct answer was

Or p < -2, because you could move it either down or up.
but if you moved it down, the graph would still cut through the x-axis and thus give real roots

They're talking about an Edexcel question, can't remember the question entirely but majority of people at my college were getting 13/12 (pi) so I'm hoping that's the right answer

I had 1 real root, which was gamma... You'd still get a crossing it it was moved up which is okay. So pretty sure it was p>2 p<-2

Oh right, I was referring to the AQA volumes of revolution question where you had to give your answer as ma^3.

Don’t use pi use theta once you’ve completed your integration divide by the integrand and you’ll get theta= 20/9 which is 2.2

The question where people are getting 2.2 radians is an equation bounded between x=8 and x=1/8

Did stats and mechanicz, went much better than paper 1. Anyone else remember their answers, I got 1 17m/s^2 for the a celebration of the truck and 4020j lost for the slide

did you mean 1.17? If so I got the same!! And I think I got around that for the energy lost too - if I'm honest, the paper has been erased from my mind though, not a mechanics fan at all! 🤣

Yeah I meant 1.17, mechanics was the topic that stopped me from ending it all

How did everyone find it? It was hard to finish everything in time. Can we start an unofficial markscheme for today's paper? Thank you!!
