About Nabla and index notation Physics Forums
Del, or nabla, is an operator used in mathematics (particularly in vector calculus) as a vector differential operator, usually represented by the nabla symbol ∇. When applied to a function defined on a one-dimensional domain, it denotes the standard derivative of the function as defined in calculus. When applied to a field (a … See more Del is used as a shorthand form to simplify many long mathematical expressions. It is most commonly used to simplify expressions for the gradient, divergence, curl, directional derivative, and Laplacian. Gradient See more For vector calculus: For matrix calculus (for which $${\displaystyle {\vec {u}}\cdot {\vec {v}}}$$ can be written $${\displaystyle {\vec {u}}^{\text{T}}{\vec {v}}}$$): See more • Del in cylindrical and spherical coordinates • Notation for differentiation • Vector calculus identities See more When del operates on a scalar or vector, either a scalar or vector is returned. Because of the diversity of vector products (scalar, dot, cross) … See more Most of the above vector properties (except for those that rely explicitly on del's differential properties—for example, the product rule) rely … See more • A survey of the improper use of ∇ in vector analysis (1994) Tai, Chen See more WebSep 6, 2024 · You need to use \imath and \jmath instead of unit vectors i and j.
