Hello, I'm currently working myself through Spivak, and that was after I've worked through most of "Book of Proof"; even then Spivak proved to be exceedingly tough. It is really a whole other ball game compared to anything you may have learned in school. I'm not sure about the "No BS Guide"...

How did you deduce that ##h(x)## is constant on ##(a,b)##? PeroK has a very good suggestion, under what conditions would ##h(x)## be constant over an interval? Could this have something to do with its derivative?

I don't have a license and I'm not sure I intend to get one anytime soon, public transport is efficient enough to get me where I want for now :rolleyes:

Ha! I knew what that would be before I even clicked the link :DD

Have you studied Vector Analysis yet? I'm reading out of Schaum's "Vector Analysis with an introduction to Tensor Analysis", my instructors think that the latter portion on tensors is good.

Yes I can see it now, looks interesting, I'll have a go at it.

Hey diredragon, maybe you could try to post the picture file once more, I don't seem to be able to see it.

The US may have done a slightly better job, but I doubt that they have the situation under control either. I believe the Fort Hood shootings were also similarly motivated. As for whether or not the US have done a good job integrating Muslims, I feel that they have integrated better since they...

This is terrible! My thoughts go to the families of those killed .

How about draw some forces? In particular, tension will be useful here.

No they are not necessarily the same, that's why the two weights are differentiated in the answer. BvU is requesting you to upload your attempt at solving the question, please do that so that we may help you :approve:

You could try to recall the relationship between force and momentum, that would explain how the soldier stays in the air.

Like haruspex said, the masses don't matter, they'll cancel out. Keep in mind that the total initial energy possessed by the sphere will be comprised of rotational and translational kinetic energy.
