Apr9 asked exponential and gamma distribution, survival functions Feb18 comment Prove the sequence $x_n = \frac{x_{n-1}}{2}+\frac{A}{2x_{n-1}} \rightarrow \sqrt{A}$ as $n \to \infty$ Thanks! There was also a follow-up question: what happens if x_0 < 0? I'm not sure about this, other than just to say there are no real roots. I don't think that's the expected answer. I think that means, it violates some assumptions of banachs fixed point theorem? Perhaps that it's monotonic and/or bounded? Really not sure.

Dec10 comment Help me understand a surface integral question? Where did the root(14) go in your integral? I'm sorry. I'm not familiar with integrating a surface integral without reparameterizing in terms of vectors first. I'm just learning these things now. Dec10 comment Help me understand a surface integral question? Thank you very much. So, the limits of integration would literally just be 0 <= u <= 3 and 0 <= v <= 2. I've just never seen this notation, and didn't want to assume [0,3] was x and [0,2] was y. Thank you! Dec10 asked Help me understand a surface integral question? Nov27 awarded Scholar
