Web2 Answers. The partial-derivative symbol is ∂. One of the first known uses of the symbol in mathematics is by Marquis de Condorcet from 1770, who used it for partial differences. The modern partial derivative notation is by Adrien-Marie Legendre (1786), though he later abandoned it; Carl Gustav Jacob Jacobi re-introduced the symbol in 1841. WebThe reason for a new type of derivative is that when the input of a function is made up of multiple variables, we want to see how the function changes as we let just one of those variables change while holding all the others constant. With respect to three-dimensional …

WebFeb 17, 2024 · 1. Im new to the Tensor Calculus and General Theory of Relativity, and I have one question. I want to determine the Christoffel symbols in FRW metric. This is the general equation of Christoffel symbols: Γ μ α β μ = 1 2 g μ ν [ ∂ g α ν ∂ x β + ∂ g β ν ∂ x α − ∂ g α β ∂ x ν] So the g μ ν in the expanding FRW ... WebTo get a general df/dx and df/dy equation, it's easier to use the method in the section "Partial derivatives, introduction." You can use the formal definition to find a general derivative equation for most functions, but it is much more tedious, especially with higher polynomial functions.

The character ∂ (Unicode: U+2202) is a stylized cursive d mainly used as a mathematical symbol, usually to denote a partial derivative such as (read as "the partial derivative of z with respect to x"). It is also used for the boundary operator in a chain complex, and the conjugate of the Dolbeault operator on smooth differential forms over a complex manifold.
