Resposta:

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

Explicació:

# "Com" | sin (x) | <= 1 "i" arctan (x) / x> = 0, "tenim" #

# | (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))) "(tots dos arctan (x) / x i" 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))) #
