"प्रतिलोम त्रिकोणमितीय फलन": अवतरणों में अंतर

| 0 < ''y'' < π || 0° < ''y'' < 180°

| '''arcsecant''' || ''y'' = arcsec&nbsp;''x'' || ''x'' = [[Trigonometric functions#Reciprocal functions|sec]]&nbsp;''y'' || ''x'' ≤ −1 or 1 ≤ ''x'' || 0 ≤ ''y'' < π/2 or π/2 < ''y'' ≤ π || 0° ≤ ''y'' < 90° or 90° < ''y'' ≤ 180°

:<math>\sin(y) = x \ \Leftrightarrow\ y = \arcsin(x) + 2k\pi \text{ or } y = \pi - \arcsin(x) + 2k\pi</math>

:<math>\cos(y) = x \ \Leftrightarrow\ y = \arccos(x) + 2k\pi \text{ or } y = 2\pi - \arccos(x) + 2k\pi</math>

:<math>\tan(y) = x \ \Leftrightarrow\ y = \arctan(x) + k\pi</math>

:<math>\cot(y) = x \ \Leftrightarrow\ y = \arccot(x) + k\pi</math>

:<math>\sec(y) = x \ \Leftrightarrow\ y = \arcsec(x) + 2k\pi \text{ or } y = 2\pi - \arcsec (x) + 2k\pi</math>

:<math>\csc(y) = x \ \Leftrightarrow\ y = \arccsc(x) + 2k\pi \text{ or } y = \pi - \arccsc(x) + 2k\pi</math>
