Bab 2 Latihan 2.1.1.1 Latihan 1

x <- 10
slice_plot(A * x ^  2 ~ A, domain(A = range(-2,  3)))

Jelaskan mengapa grafik tersebut tidak terlihat seperti parabola, meskipun merupakan grafik dari Ax2

JAWABAN: Perhatikan bahwa masukan ke fungsi adalah A, bukan x. Nilai dari xtelah diatur ke 10 — grafik dibuat pada rentang Adari− 2−2 ke 3.

2.1.1.2 Latihan 2

Terjemahkan setiap ekspresi ini dalam notasi matematika tradisional ke dalam plot.

A. 4x−7di jendela x dari 0 sampai 10 Jawab :

slice_plot( 4 * x - 7 ~ x, domain(x = range(0, 10) ))

B. Cos ⁡5x di jendela x dari− 1−1 ke 1 Jawab :

slice_plot( cos(5 * x) ~ x, domain(x = range(-1, 1)))

C. Cos⁡2t di jendelatdari 0 sampai 5.

Jawab:

slice_plot( cos(2 * t) ~ t, domain(t = range(0,5) ))
