	Represents a pair of Variables corresponding to sin(q) and cos(q). More...

Namespaces
namespace	drake
namespace	drake::symbolic

Typedefs
using	SinCosSubstitution = std::unordered_map<Variable, SinCos>

Enumerations
enum class	SinCosSubstitutionType { kAngle , kHalfAnglePreferSin , kHalfAnglePreferCos }

Functions
Expression	Substitute (const Expression &e, const SinCosSubstitution &subs)
	Given a substitution map q => {s, c}, substitutes instances of sin(q) and cos(q) in e with s and c, with partial support for trigonometric expansions.
template<typename Derived>
MatrixLikewise< Expression, Derived >	Substitute (const Eigen::MatrixBase< Derived > &m, const SinCosSubstitution &subs)
	Matrix version of sin/cos substitution.
symbolic::RationalFunction	SubstituteStereographicProjection (const symbolic::Polynomial &e, const std::vector< SinCos > &sin_cos, const VectorX< symbolic::Variable > &t)
	Substitutes the variables representing sine and cosine functions with their stereographic projection.
