Ok thanks for the advice! I guess it's a little bit unrealistic to work so little hours when you need to cooperate with other employees, I hadn't thought of that. It just seems that 40 hours a week leaves one with limited free time and I hear people talk about how they wished they worked less...

Hey everybody, I'm looking for some general guidance about breaking the 40 (or more) hour workweek as a chemical engineer. I'm currently majoring in chemical engineering, and so far I really enjoy learning the material and can see myself happily perusing a career in chemical engineering after I...

That makes a lot of sense, in fact you just cleared up another thing on my mind related to this topic with that answer. Thank you!

Ok so I want to preface my question with the fact that I'm not trying to present a crackpot theory, I obviously have a flaw in my logic I just need a little correcting. So I was reading about gluons and read that they had to have a mass to allow the strong force to have a limiting range. So...

How do you know S clock reads 6.25?

I'm having a hard time figuring out in problems which is proper time and which is just time, and I think it follows from my misunderstanding of time dilation. I've read my book and looked over my notes but I can't seem to figure it out. Here's an example: A person in frame S' moves with a...

Sorry, that is the answer, much thanks for the help!

Ok, I used a calculator to continue to find the next number in the sequence about 4 or 5 inputs and I start to get .7853981634... every time. This should then be the number the sequence converges to, the only problem is that the initial equation was of the form of Newton's method, which is used...

So when I try to evaluate x1 I get x1=x0+1=x0-sin(x0)cos(x0)+cos2(x0)=(1)-sin(1)cos(1)+cos2(1). How can you evaluate this?

I need to find what it converges to, so I believe that entails taking the lim as x -> ∞ but the lim of any trig function as it goes to infinity is undefined. Is that what I'm supposed to do?

Also, how could I prove that x_n converges to a limit L? Thanks for responding, I really want to get this problem, I just can't seem to get it on my own.

I'm not sure, does it also approach L?

oh sorry your supposed to show if it converges or not.

Homework Statement The following sequence comes from the recursion formula for Newton's Method. x0= 1 , xn+1=xn-(tanxn-1)/sec2xn Show if the sequence converges or diverge. Homework Equations The Attempt at a Solution I don't really know where to start on this problem, I have tried to use some...

Thanks guys I think I'm a little less worried about getting an A now, although it would be nice. I think I'm just going to try to redo homework more and maybe some other practice problems in the book.
