Ok imagine this: --1---|------2------- | 4 | |-------3------ 1 is a rigid pipe supplying air at a constant rate 2 and 3 are elongated air tight cloth bags of equal volume 4 is a rigid pipe connecting the 1,2 and 3 together Would both the bags fill...

In that case would you say that I would be on an equal starting point with everyone else(if I got the above?)

So, to clarify you are saying as long as I get a 1st from one of those Unis, a good GRE score, do a good interview and good references from lecturers etc then I should be OK to do a PhD at a good US university e.g. MIT, ivy league etc

My sister went to cambridge and really hated it. It kinda put me off... I also thought that as long as I got a 1st from a russel group uni I would be OK

Hey, I am in the process of choosing which univeristy I want to go to do my first degree. I am am also thinking about doing a PhD after I finish my first degree. I would like to do this PhD at a good international university in the US or in wider europe e.g MIT. With that in mind could...

Hi Hurkyl. I am not assuming the roots are real. Thanks

Thanks phoenixthoth. Labelling the 4 cases you have identified as set out by you a) b) c) d) i get the following solutions to each: a) b < 0 b) b > 2, b >0 which implies b > 2 OR: b < 2, b < 0 which implies b < 0 c) b > 0 d) 0 < b < 2 which doesn't give me any sections of...

Thanks phoenixthoth. Yes it was a typo and yes it was the latter and yes b is real number. But how do i proceed from here? It still seems to yield a contradiction. Thanks

Homework Statement How to find the conditions on the coefficients of a quadratic equation for the roots to be outside the unit circle eg bx^2 + x - 1 = 0 where b is a constant How do we find the condition(s) that b must satisfy such that the roots of the quadratic lie outside the unit circle...
