Arccos Graph. See the truncated-graph with asymptote y pi2 and the limiting lines y 0 and y pi. In the figure below the portion of the graph highlighted in red shows the portion of the graph of cosx that has an inverse.
Arcsine is red Arccosine is blue. The function accepts both real and complex inputs. Y acosdX returns the inverse cosine cos-1 of the elements of X in degrees.
