del
n. countablen. a mathematical symbol that looks like an upside-down triangle. You use it to show how something changes in different directions in space.
n. a vector differential operator, typically represented by the nabla symbol (∇). Used to denote the gradient, divergence, or curl of a function in vector calculus.
The del operator is used to calculate the gradient of the field.
In physics, the del symbol appears frequently in equations that describe how fluids flow or how heat moves.
Maxwell's equations are often expressed using del notation to provide a concise mathematical description of how electric and magnetic fields interact in three-dimensional space.
Often referred to as 'nabla' in mathematical contexts; functions as a differential operator rather than a standard variable.
