Anda telah melihat bagaimana memplot grafik fungsi dari satu variabel, misalnya:
slice_plot(
95 - 73*exp(-.2*t) ~ t,
domain(t = 0:20) )
pelajarannya adalah tentang memplot fungsi dua variabel. Sebagian besar, format yang digunakan adalah plot kontur.
Anda menggunakan contour_plot() untuk memplot dengan dua variabel masukan. Anda perlu mencantumkan dua variabel di sebelah kanan tanda +, dan Anda perlu memberikan rentang untuk masing-masing variabel. Sebagai contoh:
contour_plot(
sin(2*pi*t/10)*exp(-.2*x) ~ t & x,
domain(t = range(0,20), x = range(0,10)))
Kadang-kadang, orang ingin melihat fungsi sebagai permukaan, diplot dalam 3 dimensi. Anda bisa membuat komputer menampilkan plot perspektif 3 dimensi dengan menggunakan fungsi interactive_plot() . Seperti yang akan Anda lihat dengan mengarahkan mouse di sekitar plot, ini interaktif.
interactive_plot(
sin(2*pi*t/10)*exp(-.5*x) ~ t & x,
domain(t = 0:20, x = 0:10))
