In this paragraph:
>In single variable calculus, the chain rule can be written as . In the multivariable case, for a function , we write where is the partial derivative of with respect to its th argument. This can be simplified by employing the following notation, which uses a dot product: .
What does stand for?
My understanding that g maps and indicates i-th element of a vector that g produces.
Is that the right way to think about it?
