16. Hitunglah lim (sin(3x)/sin(x) saat x mendekati 0.
Jawaban: lim (sin(3x)/sin(x) = 3
17. Hitunglah lim ((tan(x) – x)/x^3) / ((sin(x) – x)/x^2) saat x mendekati 0.
Jawaban: lim ((tan(x) – x)/x^3) / ((sin(x) – x)/x^2) = 1
18. Hitunglah lim (sin(2x)/x saat x mendekati tak hingga.
Jawaban: lim (sin(2x)/x = 2
