When is a real number, sine and cosine ...
1 dzień temu · In differential geometry, a Riemannian manifold (or Riemannian space) (M, g), so called after the German mathematician Bernhard Riemann, is a real, smooth manifold M equipped with a smoothly-varying positive-definite inner product g p on the tangent space T p M at each point p.. The family g p of inner products is called a Riemannian metric (or a Riemannian metric tensor, or just a metric).
