The Nabla symbol (∇), also known as "del," is a mathematical operator primarily used in vector calculus. Its name comes from the Greek word for a type of ancient harp, which it closely resembles in shape. Beyond complex equations representing gradient, divergence, or curl, you might spot it in technical documents or occasionally used as a stylized downward-pointing triangle in digital typography.
