BTW, the value:
1/(-1,850354529) = -0,540436972651802
while cos(-1) which is the real part of -I*e^(-I) in complex plane is
cos (-1) = -0,54030230586814
The difference between infinite negative pentation of e and cos(-1) being 0,025%.
I have a feeling something is being rather closely approximated by infinite negative pentation of e (e.g. alpha, (-I*e^(-I )), ) . Where would the next steps of approximation hide?
