sincosd

Compute the sine and cosine of x expressed in degrees.

Base.Math.sincosd — Function
sincosd(x::T) where T -> Tuple{float(T),float(T)}

Simultaneously compute the sine and cosine of x, where x is in degrees, returning a tuple (sine, cosine).

Throw a DomainError if isinf(x), return a (T(NaN), T(NaN)) tuple if isnan(x).

Julia 1.3

This function requires at least Julia 1.3.
