Characterizing the metric space {N}

For the metric space { N }, the set of all natural numbers, characterize whether or not it has the following properties: compact, totally bounded, has the Heine-Borel property, complete. For compact, we are to show that every sequence converges. For totally bounded, we are to show that it can be covered by finitely many sets ...continues

Characterize the Real numbers with the Discrete Metric

Characterize the set of all real numbers with the discrete metric as to whether it is compact, complete, or totally bounded. Use definitions only! (i.e. compact => every sequence converges, etc)

Show that a subset can be covered by one open ball

If a subset A of a metric space X has diameter less than epsilon, then it can be covered with one open ball of radius epsilon. Prove. (We must use direct definitions only for the proof).

Using Mathematica

I am new to Mathematica and did derive the answer to the following but I can not get the information as to the steps taken to derive it. I am using the trapezoidal and Simpson's rules to evaluate S20 x2 dx ( the S should be the variant symbol) Compare with exact value. My answer is 8/3 but I can not get Mathema ...continues

bisection and newton methods

I have a quation in numerical analysis subject.you have to use the matlab software to solve it. Q Using the bisection method, find the positive root of 2x(1 + x^2)^-1 = arctan x. Using this root as x0; apply Newton's method to the function f(x) = arctan x: Interpret the results you obtain.
