Question

when does earthly power show like God's?​

Answer 1

Let's approach it elementarily:

limx→01−cos(1−cosx)x4=limx→0sin2(1−cosx)x4(1+cos(1−cosx))=limx→0sin2(1−cosx)2x4=

limx→0(sin(1−cosx)(1−cosx))2⋅12limx→0(1−cosxx2)2=18.

NOTE: for the above limit i resorted to the auxiliary limit:

limx→01−cosxx2=limx→0sin2xx2(1+cosx)=12.
