WebMar 5, 2024 · In other words, there is no sensible way to assign a nonzero covariant derivative to the metric itself, so we must have ∇ X G = 0. The required correction therefore consists of replacing d / d X with. (9.4.1) ∇ X = d d X − G − 1 d G d X. Applying this to G gives zero. G is a second-rank tensor with two lower indices.

WebHere's a plain-English description of what the P, I, and D in PID control theory stand for: P: the further you are from where you want to be, the harder you should try to get there. I: the longer you haven’t been where you want to be, the harder you should try to get there. D: if you’re quickly getting close to where you want to be, slow down.
