I am not removing lim n->infinity ,thats why I m writing like this ,,as shown in video provided by u,including lim is changing to integral

bhai u have changed sigma to integral directly...we can't do like this... sigma gives discrete summation..here it will be 1+2+3+....+n... but integral gives continuous summation like to find the total electric charge in a body then we have to use integral not sigma.. continuous summation from 1 to n  is like 1+ 1.01+1.001 + 1.000001 + 2 + 2.01+...+n...
