The symbol is variously referred to as "partial", "curly d", "rounded d", "curved d", "dabba", or "Jacobi's delta", or as "del" (but this name is also used for the "nabla" symbol ∇). It may also be pronounced simply "dee", "partial dee", "doh", or "die". The Unicode character U+2202 ∂ PARTIAL DIFFERENTIAL is accessed … See more The character ∂ (Unicode: U+2202) is a stylized cursive d mainly used as a mathematical symbol, usually to denote a partial derivative such as $${\displaystyle {\partial z}/{\partial x}}$$ (read as "the partial derivative of … See more ∂ is also used to denote the following: • The Jacobian $${\displaystyle {\frac {\partial (x,y,z)}{\partial (u,v,w)}}}$$. • The boundary of a set in topology. • The boundary operator on a chain complex in homological algebra. See more The symbol was originally introduced in 1770 by Nicolas de Condorcet, who used it for a partial differential, and adopted for the partial derivative by Adrien-Marie Legendre in 1786. It represents a specialized cursive type of the letter d, just as the integral sign originates as a … See more • d'Alembert operator • Differentiable programming • Differential operator § Notations See more WebHere ∂ is a rounded d called the partial derivative symbol. To distinguish it from the letter d, ∂ is sometimes pronounced "tho" or "partial". That statement about "tho" sounds somewhat rediculous and a bit speculative. How do math professors actually pronounce it in their lectures? Upd. 3blue1brown has a video about it. And he calls them ...
