With Student MultivariateCalculus, (or LinearAlgebra, or VectorCalculus) loaded, the norm defaults to the Euclidean norm. This norm in the Student MultivariateCalculus package can be accessed either from the Context Panel, or directly, with Typeset math.

The subscript on the norm forces Maple to compute the 2norm, that is, the Euclidean norm. At top level, with no relevant package loaded, Maple's norm (computed via Typeset math notation) is the largest absolute value of the components, the default for the LinearAlgebra package.
