Why do the limits of the following two equations have opposite signs? (MATLAB R2024a Update 1 _20240418)
limit((1-(-1)^n)/n, n, 0) have two results, and Matlab only gets one of them. (1-(-1)^n) = (1+(1i)^n)*(1-(1i)^n) or (1-(-1)...

Why do the limits of the following two equations have opposite signs? (MATLAB R2024a Update 1 _20240418)
Why limit((1-(-1)^n)/n, n, 0) = -pi*1i ? limit((1-exp(-pi*n*1i))/n, n, 0) = pi*1i limit((1-(-1i)^n)/n, n, 0) = limit((1-exp(-p...
