Arccos Graph Function. On this interval the cos x has an inverse function denoted by y arccos x or y cos 1x. Free online calculators and tools.
Arccosine written as arccos or cos-1 not to be confused with is the inverse cosine function. Simply enter the expression according to x of the function to be plotted using the usual mathematical operators. Arccos cos x x2kπ k is an intager sin x cos π2-x.
BackgroundThe arccosine function is the inverseof the cosinefunction as long as the cosine function is restricted to a certain domain.
Cosine only has an inverse on a restricted domain 0xπ. The inverse cosecant function denoted by csc 1 x or arccscx is de ned to be the inverse of the restricted cosecant function cscx. For example inverse sine and inverse cosine are rather abrupt and disjointed. Click here for a review of inverse functions.
