That's it. Eq.1) where E ⁡ [X] {\displaystyle \operatorname {E} [X]} is the expected value of X {\displaystyle X} , also known as the mean of X {\displaystyle X} . The covariance is also sometimes denoted σ X Y {\displaystyle \sigma _{XY}} or σ (X , Y) {\displaystyle \sigma (X,Y)} , in analogy to variance . By using the linearity property of expectations, this can be simplified to the expected value I'm having some trouble understanding the covariant derivative as a directional derivative for tensors. The way the covariant derivative was presented to me was by first showing that a vector field can provide a directional derivative for smooth functions on a manifold. In theoretical physics, general covariance, also known as diffeomorphism covariance or general invariance, consists of the invariance of the form of physical laws under arbitrary differentiable coordinate transformations. Covariance is the measure of changes between two random variables in statistics.

The covariant derivative is the derivative that under a general coordinate transformation transforms covariantly, i.e., linearly via the Jacobian matrix of the coordinate transformation.

One can motivate the covariant differentiation using only vector calculus. It works for an oversimplified case though (but since the OP doesn't accept either the definition via Ehresmann connection nor the vector bundle definition, may be it's justified.) Many text books on differential geometry motivate covariant derivative more or less by saying that if you have a vector field along a curve on a manifold (that is a curve $\gamma(t)$ and an assignm Metric compatible. In the coordinate-specific section of this article, it is stated "By the way, this particular expression is equal to zero, because the covariant derivative of a function solely of the metric is always zero.".
