Untuk menghitung luas dibawah dua kurva atau fungsi, kita bisa menggunakan perintah Integral lihat http://www.geogebra.org/help/docuin/index.html di bagian Perintah-Perintah atau akses Bantuan.

Integral[fungsi f, fungsi g, angka a, angka b]
Integral tertentu dari perbedaan fungsi f(x) - g(x) dari nilai a ke nilai b. Contohnya:
Integral[f(x), fungsi g(x), 1, 2]
Dalam animasi di bawah ini, semua parameter fungsi dan batas-batas fungsi dibuat dinamis dengan bantuan slider/Luncuran. Silahkan anda explorasi contoh berikut dengan menggeser nilai a, b, c,  k, l, m, n, v, atau w.
