Parameters

x  Double

The argument.

Return Value

The entire cosine integral Cin(x) is related to the conventional cosine integral Ci(x) by:

Unlike Ci(x), Cin(x) is regular at the origin, and may therefore be more useful in applications that need the non-divergent part of a cosine integral. In fact, Cin(x) is entire, meaning it has no poles or cuts anywhere in the complex plane. But, unlike Ci(x), Cin(x) does diverge (logarithmicaly) for large x.
