Classes
struct	stan::math::cos_fun
	Structure to wrap cos() so it can be vectorized. More...

Namespaces
namespace	stan
	The lgamma implementation in stan-math is based on either the reentrant safe lgamma_r implementation from C or the boost::math::lgamma implementation.
namespace	stan::math
	Matrices and templated mathematical functions.
namespace	stan::math::internal
	A comparator that works for any container type that has the brackets operator.

Functions
template<typename Container , require_not_container_st< std::is_arithmetic, Container > * = nullptr, require_not_var_matrix_t< Container > * = nullptr, require_all_not_nonscalar_prim_or_rev_kernel_expression_t< Container > * = nullptr>
auto	stan::math::cos (const Container &x)
	Returns the elementwise cos() of the input, which may be a scalar or any Stan container of numeric scalars.
template<typename Container , require_container_st< std::is_arithmetic, Container > * = nullptr>
auto	stan::math::cos (const Container &x)
	Version of cos() that accepts std::vectors, Eigen Matrix/Array objects or expressions, and containers of these.
template<typename T >
std::complex< T >	stan::math::internal::complex_cos (const std::complex< T > &z)
	Return the cosine of the complex argument.
