I'm not really sure how to calculate this. At this point, we don't have explicit formulae for the coefficients of a Laurent series so I really don't know what to...
Hi All,
I was reading through Kreyzeig's Advanced Engineering Mathematics and came across two theorems in Complex Analysis.
Theorem 1:
Let f(z) = u(x,y) + iv(x,y) be defined and continuous in some neighborhood of a point z = x+iy and differentiable at z itself.
Then, at that point, the...
So this is what I have so far.
x_0 = r r is a non-zero real number
x_{n+1} = x_n(\frac{1}{2} + \frac{c}{2x_n^2}) Case 1: ##r^2 < c~ \Rightarrow## sequence is increasing
Case 2: ##r^2 > c ~\Rightarrow## sequence is decreasing
So, I have an idea, but I'm not sure if it proves convergence.
If x_{n} = g(x_{n-1}) then all I have to do it let x = g(x).EDIT: Upon further thought, it does not as convergence => x_{n} = g(x_{n-1}). It is not a iff situation. Back at square one.
Homework Statement
Prove for c>0 the sequence {x_n} = \frac{1}{2}(x_{n-1} + \frac{c}{x_{n-1}}) converges.
The Attempt at a Solution
This is proving difficult, I have never dealt with recursive sequences before. Any help would be appreciated. Thanks.
Hey guys,
In a bit of a sticky situation here. So, there is a prof. who wants me to work with him over the summer and then into the future, the issue is, his area of research is NOT what I see myself doing or even interesting.
My question is, how would you tell him that you would rather...

One thing that really helps me calm my nerves during a test is to go through it methodically. I do this by:
1. Assuming that I am an average or above average student with regards to time required to take the test. Therefore, I do not have to worrry about time as longa s I go at my own (typical)...
