    Is This Piecewise Function Riemann Integrable?

    Ok, but how to prove it? It has to do with that sequence because on each interval [n, n+1) it is equal to (1/n+1)(-1)^n.

    Is This Piecewise Function Riemann Integrable?

    let f(x) = 1 when x in in [0,1) f(x) = -1/2 when x is in [1,2) f(x) = 1/3 when x is in [2, 3) and so on, in othe words its the sequence (1/n)(-1)^n, whose series obviously converges to log 2. However is f(x) Riemann integrable and equal to this series? If so, how to give an...

    Complex Contour Integral: Does it Equal 0?

    Right, that is what I thought, since its a removable singularity, the residue at zero is zero, then the integral of that function is zero. thank you everybody

    Complex Contour Integral: Does it Equal 0?

    Thank you for the replies, but this is no where near as complicated. y=e^(2(pi)(i)(t)) 0=<t=<1 is indeed a closed contour, since e^(2(pi)(i)) = e^0. My question was am I right in assuming that the function is analytic (equivalently differentiable) on the domain inside the contour, if it...

    Complex Contour Integral: Does it Equal 0?

    Hi, Does this complex contour integral equal 0? [Int] (z^2)/(sin z) dz along the closed contour e^2(pi)(i)(t) 0<t<1 It should equal zero cause its analytic in the domain around te curve and the zero in the numerator is of higher order than the zero in the denominator at the point z=0...
