Answer 1

Jawaban:

[Limit Trigonometri]

Penjelasan dengan langkah-langkah:

lim ₓ→π/4 sin x = Sin π/4

= Sin (180/4)

= Sin (45)

= 1/2√(2)

lim ₓ→π/12 Sin x = Sin (π/12)

= Sin (180/12)

= Sin (15)

= 1/4(√6-√2)

Sin (45-30) = Sin 45 Cos 30 - Cos 45 Sin 30

= 1/2√(2) 1/2√(3) - 1/2√(2) 1/2

= 1/4√(6) - 1/4√(2)

= 1/4(√6-√2)
