7.5. Components and derivatives

ComponentValue also works with derivatives of tensors (but not for more general expressions, you can use Coba as a placeholder and then substitute the expression). Remember that with our definitions the components of the derivative are not the derivatives of the components.

Derivatives are represented by additional central arguments in ValID:
