Daftar integral dari fungsi invers trigonometri

Daftar integral (antiderivatif) dari ekspresi yang melibatkan fungsi invers trigonometri. Untuk daftar lengkap rumus integral, lihat tabel integral.

• Fungsi invers (= "fungsi kebalikan") trigonometri juga dikenal sebagai "fungsi arc" ("arc functions").
• C digunakan untuk melambangkan konstanta integrasi arbitrari yang hanya dapat ditentukan jika nilai integral pada satu titik tertentu telah diketahui. Jadi setiap fungsi mempunyai antiderivatif yang tak terhingga banyaknya.
• Ada tiga notasi umum untuk fungsi-fungsi invers trigonometri. Fungsi arcsinus, misalnya, dapat ditulis sebagai sin⁻¹, asin, atau, pada halaman ini, arcsin.
• Untuk setiap rumus integrasi fungsi invers trigonometri di bawah ini ada rumus yang bersangkutan dalam daftar integral dari fungsi invers hiperbolik.
