Odgovor:

# | sin (x) | <= 1, "in" arctan (x) / x> = 0 #

Pojasnilo:

# "As" | sin (x) | <= 1 "in" arctan (x) / x> = 0, "imamo" #

# | (sin (1 / sqrt (x)) arctan (x)) / (x sqrt (ln (1 + x))) | <= | arctan (x) / (x sqrt (ln (1 + x))) | #

# = arctan (x) / (x sqrt (ln (1 + x))) "(tako arctan (x) / x kot" sqrt (…)> = 0 ")" #

# = arctan (x) / (sqrt (x) sqrt (x ^ -1) x sqrt (ln (1 + x))) #

# = arctan (x) / (sqrt (x) x sqrt (x ^ -1 ln (1 + x))) #
