Use the following approximation formula to find the approximation of the reciprocal of the base e of the natural logarithm.1 / e = 1-1 / 1! +1/2! -1/3! +1/4! － ・ ・ ・Lets observe how the reciprocal of the base e of the natural logarithm can be obtained as the number of terms increases.It can be observed that the convergence speed is very fast.
