Inverse trigonometric functions are widely used in engineering, navigation, physics, and geometry. For a circle of radius 1, arcsin and arccos are the lengths of actual arcs determined by the quantities in …

Arccosine, written as arccos or cos -1 (not to be confused with ), is the inverse cosine function. Both arccos and cos -1 are the same thing. Cosine only has an inverse on a restricted domain, 0 ≤ x ≤ π. …

Arccosine is the inverse cosine function and thus it is one of the inverse trigonometric functions. Learn more about arccosine function along with its graph, domain, range, graph, derivative, and integral.
