We expect the arccos of 1 to be 0, and of -1 to be pi:Īrray of the same shape as `x`, in which to store the results. Stegun, "Handbook of Mathematical Functions", The inverse `cos` is also known as `acos` or cos^-1. Has branch cuts `` and `` and is continuous fromĪbove on the former and from below on the latter. It yields ``nan`` and sets the `invalid` floating point error flag.įor complex-valued input, `arccos` is a complex analytic function that The angle `z` whose real part lies in ``.įor real-valued input data types, `arccos` always returns real output.įor each value that cannot be expressed as a real number or infinity, `arccos` is a multivalued function: for each `x` there are infinitely Scalar is returned, otherwise an array of the same shape as `x` The angle of the ray intersecting the unit circle at the given `doc.ufuncs` (Section "Output arguments") for more details.
