    What is the region of functions in C[0,1] defined by the sup metric?

    I'll try that and see how I get on then. Thanks so much for your suggestion. Cheers!

    Double Integration: Evaluating z^2 = x^2 + y^2

    Hi I've been working on a problem and I'm nearly there but I'm struggling with the integration part at the end and was hoping you might be able to help if you have the time. The original question was \int \int (y^2 z^2 + z^2 x^2 + x^2 y^2) \: dS Evaluated on the region of z^2 = x^2 + y^2...

    What is the region of functions in C[0,1] defined by the sup metric?

    Hi there I have a proof that I need to try to work out but I'm not really getting too far and need help if you could at all. The question is Consider C [0,1] with the sup metric. Let f:[0,1]→R be the function given by f(x)=x²+2. Let B={g Є C[0,1]: 1 ≤ d(g,f) ≤ 3} Describe the region in...

    How Can I Prove These Topology Statements?

    Hello I have a proof that I need to try to work out but I'm not really getting too far and need help if you could at all. The question is Let A and B be two subsets of a metric space X. Prove that: Int(A)\bigcupInt(B)\subseteqInt(A\bigcupB) and Int(A)\bigcapInt(B) = Int(A\bigcapB) I...
