Materi :Limit
Penjelasan dengan langkah-langkah:
1. Lim (x³-8)/(x²+2x-8)
= Lim (x³-2³)/((x+4)(x-2))
= Lim ((x-2)(x²+2x+4))/((x+4)(x-2))
= Lim (x²+2x+4)/(x+4)
subtitusikan 2 ke x
= (2²+(2(2))+4)/(2+4)
= (4+4+4)/6
= 12/6
= 2

2. Diketahui:
s = f(t) = 3t²
Ditanyakan:
v saat t= 10
Jawab:
v = f'(t) = 6t
f'(10) = 6(10) = 60
