Hey guys, i was doing past papers for eco and i was completely stumped on this question. Could any of you guys please explain.

oh wait...logs

thanks alot mate. Makes sense now. Integration for this question is such a bitch

I need help. I dont know how to do this. The region between the curves y=1/(x+1) and y=1/(x-5) and y-axis and line x=2 is rotated about the line x=2. Find volume using shells method

Here is an example A ball is thrown at an angle alpha to the horizontal from the top of a very high building. Its initial velocity is u. It experiences air resistance of mkv directed against each of the x and y components of its motion. Its vertical component also experiences effect of gravity...

lol

Hey guys. I have my trial very soon and i can't get my head around resisted projectile motion. Any tips or handy hints that will make life easier?

I got that answer too!!!

Damn, how careless!

which radius we subtract from the other radius? is it pi[(x^2-1)^2 -(-0.5x)^2]delta x or pi[(-0.5x)^2 - (x^2-1)^2]delta x

Haha, I'm not particularly smart or anything. If u dont mind me asking, what school do u go to? If I can survive first week of trials I will be relieved. English on Tuesday, Ext 2 on Wednesday and English paper 2 on Thursday. At the end of next week, I am done.

Yes pls

I do indeed go to girra. Trial period has just started. I have my first exam on tuesday, extension 2 is on Wednesday. Thanks, I need all the luck I can get. U have ur trials yet?

Thanks man, that was very well explained

Is the answer 27pi / 40(root2) units cubed?

Wouldn't using shells give u a delta y

Could u think of an example where it would not be better to use shells cos i find that i am trying to use shells for everything.

Only unity? Every test, we had at our school there was a question like this

thankyou. much appreciated

Could u please show full answer pls. I think I forgot how to use the 2k pi
