    Sir, at 9:01 you didnt cancel out the 2. You will get an extra 2 in the numerator because you forgot the 2 at 4:46. Otherwise, great job sir!

      Yes, and there is no error in the solution. I think the result will be without '2' in the numerator. I was also confused there.

    • @Harshit_Pro
      @Harshit_Pro 3 роки тому +8

      He forgot 1 step, when substituting z=e^(i theta), the limits of the integral would become z=-1 to z=1, so in the answer there is no z, so we will get (pi)/(root(a^(2)-b^(2)))+(pi)/(root(a^(2)-b^(2)))=(2pi)/(root(a^(2)-b^(2)))

  • @darkseid856
    @darkseid856 4 роки тому +6

    Sir one thing I noticed is that in all of these problems we had limit from 0 to 2π . So what if we had different limits . For example, 0 to π/2 or -π to 3π/2 ...etc .
    Because when we convert our original function into a complex function and solve it using contour integration which has no limits of integration but instead a closed contour .

    • @fatimaalishah1881
      @fatimaalishah1881 4 роки тому +3

      If limit would be 0 to π/2 then the contour will only lie in quadrant 1 and hence would not be closed.
      Usually we consider a circle as contour which swept 2π angle
