Question

Soal tentang limit trigonometri. tolong bantu kerjain :) pake caranya

Answer 1

1.
lim x^3 - 64 / (x - 4)
x➡4
= lim (x - 4) (x^2+4x+16) / (x-4)
x➡4
= 4^2 + 4(4) + 16
= 48 (D)

2.
lim 4x - x^3 / 2x^3 + x^2 + 5
x➡~
= [(4x/x^3)-(x^3/x^3)] / [(2x^3/x^3) + (x^2/x^3) + (5/x^3)
= -1/2 (A)
semoga membantu
