Bab Limit
Matematika SMA Kelas XI

Lim (√4x / (√sin 2x))
x→0

= Lim √(4/2)
...x → 0

= √2

jawabannya A

BAB LIMIT FUNGSI TRYGONOMETRY

= LIM X>0 (√4x /√ sin 2x)

= LIM X>0 ( √4x / √ sin 2x) . (√4x / √4x) . (√2x /√2x)

= LIM X>0 (√4X/√4x) . ( √ sin 2x /√2x ) . (√4x/√2x)

= LIM X >0 ( 1 ) . ( 1 ) . √( 4/2)
= 1 . 1 . √2
= √2
