For example, if $\gamma$ is a smooth plane curve that traces out the unit circle, one can easily construct a sequence of increasingly oscillatory discrete curves that converge pointwise to $\gamma$.To find the unit tangent vector for a vector function, we use the formula T (t)= (r' (t))/ (||r' (t)||), where r' (t) is the derivative of the vector function and t is given. We’ll start by finding the derivative of the vector function, and then we’ll find the magnitude of the derivative. Those two values will give us everything we need in ...The Riemann curvature tensor is also the commutator of the covariant derivative of an arbitrary covector with itself:;; =. This formula is often called the Ricci identity. This is the classical method used by Ricci and Levi-Civita to obtain an expression for the Riemann curvature tensor. This identity can be generalized to get the commutators for two covariant derivatives of arbitrary tensors ...
