lim x mendekati tak hingga (1-cos kuadrat x) : x sinx

Kelas 11 Matematika
Bab Limit

lim (1 : cos² x)/(x . sin x)
x→∞

= lim (sin² x)/(x . sin x)
   x→∞

= lim ((sin x)/x) . ((sin x)/(sin x))
   x→∞

= 1 . 1
= 1

lim (1 : cos² x)/(x . sin x)
= lim (sin² x)/(x . sin x)
= lim ((sin x)/x) . ((sin x)/(sin x)
= 1 . 1
= 1
