Inverse trigonometric functions
Arcsine, arccosine and arctangent, and the angles they return.
Arcsine
f(x) = \arcsin x = \sin^{-1} x
The arcsine function arcsin(x), the inverse of sine: domain [−1, 1], range [−π/2, π/2], graph, derivative 1/√(1−x²), integral and examples.
Arccosine
f(x) = \arccos x = \cos^{-1} x
The arccosine function arccos(x), the inverse of cosine: domain [−1, 1], range [0, π], graph, derivative −1/√(1−x²), integral and examples.
Arctangent
f(x) = \arctan x = \tan^{-1} x
The arctangent function arctan(x), the inverse of tangent: domain all reals, range (−π/2, π/2), graph, derivative 1/(1+x²), integral and examples.
