Question

f(x) = sin³ (5x + 8) memiliki turunan ........
     
A. 15 sin² (5x + 8) sin (5x + 8)
B. 15 sin² (5x + 8) cos (5x + 8)
C. 15cos² (5x + 8) cos (5x + 8)
D. 15 sin (5x + 8) cos (5x + 8)

Answer 1

Jawaban:B     

PENJELASAN:

f(x) = sin³ (5x + 8)
f'(x) = 3 sin² (5x + 8) . cos (5x + 8)
f'(x) = 15 sin² (5x + 8) cos (5x + 8)
