    Existence of the Square Root Proof

    Now I'm lost again. We are trying to prove that the LUB^2 (LUB=b) cannot be any other value but a. From this point on I don't follow the proof at all. For instance to test if LUB^2>a he sets a number c=b-(b^2-a)/(2b). Where did that come from?

    Existence of the Square Root Proof

    I was playing trying to work through a proof in Apostol's Calculus and can't quite understand a step noted. This is from chapter 3, theorem 1.35. Every nonnegative real number has a unique nonnegative square root. The part where you are establishing the set S as nonempty so you can use LUB it...

    Failed to graduate but landed a full time job

    Let me give you a word of advice. I just went through a long vetting process for a new job I am taking.

    Can someone say me what is the advantage of

    What exactly is the application? The main reason you would choose to go with an angular contact is if significant thrust loads are involved. The back to back <> would accomidate thrust loads moving in both directions where the >> is normal for just one. Double row bearings do have similar...

    Treatment of Inequalities

    I've been playing around with some proofs and find myself relearning how I do my mathmatical thinking. Just a general question regarding how to handle something like this. 0<a<b So a and b must be positive a/2 <b I just divided one side by two instead of "dividing through" like you...

    News The Case for Small Government

    This all sounds like a really good case for zero based budgeting. There is no reason why a department (at least every few years) must rejustify every dollar being allocated to it. With regards to entitlements, I believe the very same concept could be applied there as well.

    How do you get in the loop?

    I would say this is absolutely the biggest plus to any job search. Get out there and don't be affraid to meet people. You would be supprised how many opportunities come through networking. Even if you meet someone who can't help you that very moment, the world is very small. This is also why...

    Is modern banking fraud?

    Just for FYI here, if a bank has 100 dollars in cash deposits it simply cannot lend 1000 dollars out. It's not that simple. Banks are required to meet very strict capitalization requirements set by the FED. Riskier investments (bank assets) do not hold the value as a pecentage when...

    What is the Federal Reserve?

    X^n<y^n n is odd

I have used 2k+1 for n and have tried to factor it out giving this (x^{k}x^{1/2}+y^{k}x^{1/2})(x^{k}x^{1/2}-y^{k}x^{1/2}) which is just one big circle because this only yeilds a \sqrt{x^{n}}= \sqrt{y^{n}}.

    No, I would assume all 20 for N. The bond issuer still has an interest liability on that date. Let's say you purchase a bond right before the day the coupon payment is due, that almost 6 months worth of coupon payment would be baked into the price you would have to pay for the bond. Whoever...

    Business Math

    The wording of the problem is a little confusing but I would venture to guess that the 8% is the coupon rate, and the 10% is the YTM. PMT in your financial program would be (Coupon Rate X Face Value)/2 since it is semi. The I value would be 10%. This should get you started.
