Daftar integral dari fungsi trigonometri

Daftar integral (antiderivatif) dari fungsi trigonometri. Untuk antiderivatif yang melibatkan baik fungsi eksponensial dan trigonometri, lihat Daftar integral dari fungsi eksponensial. Untuk daftar lengkap fungsi-fungsi antiderivatif, lihat Tabel integral. Untuk antiderivatif khusus yang melibatkan fungsi trigonometri, lihat Integral trigonometri.

Umumnya, jika fungsi $\sin(x)$ adalah suatu fungsi trigonometri, dan $\cos(x)$ adalah turunannya,

$\int a\cos nx\;\mathrm {d} x={\frac {a}{n}}\sin nx+C$

Dalam semua rumus, konstanta a diasumsikan bukan nol, dan C melambangkan konstanta integrasi.
