Fuck bos community, full off bullsht, i'm leaving.

What do you mean by memorising formulae, in maths you don't memorise shit, you derive it.

No need to ever use cylindrical shells like this :)

whaaat, they never teach this technique to us :(

How do you change this to x^2cosx

2\pi \int_{0}^{\frac{\pi }{2}} x(1-sinx)dx WORKS !!!

[ tex ] 2\pi \int_{0}^{\frac{\pi }{2}} x(1-sinx)dx [ /tex ] Doesn't work :(

How can you copy/past latex? It doesn't work for me.

You are integrating this: 2\pi \int_{0}^{\frac{\pi }{2}} x(1-sinx)dx Type this in http://www.codecogs.com/latex/eqneditor.php to make it easier to read. For some reason I can't post latex.

I get 4a^2/3 which is half the required, something went wrong.

It says the focal chord is perpendicular to the axis, therefore you are looking at the area between y=0 and y=a. So just integrate x=(4ay)^0.5 in that limit, I think you should get the area.

Ok, I'll try control myself, but seriously, I'm wasting too much time here :(

True. Well, my maths teacher took photos of our class and she posted them to her Facebook with out permission, so annoying...

I'm really curious to what you guys look like, can you post pics if you took any at the meet? :)

Carrot, why you no free up some space to tutor me some harder MX2 :( hope Sean has some space, need a good MX2 tutor asap, looks like I'll not get one :'(
