NettetCompute ∫∞ 0 dx 1 + x3 by integrating 1 1 + z3 over the contour γ (defined below) and letting R → ∞. The contour is γ = γ1 + γ2 + γ3 where γ1(t) = t for 0 ≤ t ≤ R, γ2(t) = Rei2π 3t for 0 ≤ t ≤ 1, and γ3(t) = (1 − t)Rei2π 3 for 0 ≤ t ≤ 1. So, the contour is a wedge, and by letting R → ∞ we're integrating over one third of the complex plane. Nettet11. apr. 2015 · ∫ 1 x dx = ln x + C The reason depends on which definition of lnx you have used. I prefer: Definition: lnx = ∫ x 1 1 t dt for x > 0 By the Fundamental Theorem of Calculus, we get: d dx (lnx) = 1 x for x > 0 From that and the chain rule, we also get d dx (ln( − x)) = 1 x for x < 0 On an interval that excludes 0, the antiderivative of 1 x is

However, fun in the Question always returns a scalar for any pair of inputs. Correct fun as shown below so it returns an array the same size as x with all elements equal to 5 h ttp: gg. gg/kaitee
