  • The Dirichlet eta function is also known as the alternating zeta function.
  • DirichletEta is a mathematical function, suitable for both symbolic and numeric manipulation.
  • For , the Dirichlet eta function is defined as .
  • For certain special arguments, DirichletEta automatically evaluates to exact values.
  • DirichletEta is an entire function with branch cut discontinuities.
  • DirichletEta can be evaluated to arbitrary numerical precision.
