Derivative of incomplete gamma function
Web1. For the following upper incomplete Gamma function: Γ ( 1 + d, A − c ln x) = ∫ A − c ln x ∞ t ( 1 + d) − 1 e − t d t. I am trying to calculate the derivative of Γ with respect to x. In general it holds that: d d x Γ ( s, x) = − x s − 1 e − x. After my calculations I ended up with: WebThis function find some uses in statistical distributions: it implements the partial derivative with respect to x of the incomplete gamma function. The final Policy argument is optional and can be used to control the behaviour of the function: how it handles errors, what level of precision to use etc. Refer to the policy documentation for more ...

WebTheorem: Let $f$ be a continuous real-valued function defined on a closed interval $ [a, b]$. Let $F$ be the function defined, for all $x$ in $ [a, b]$, by $$F (x) = \int_a^x\!f (t)\, dt.$$ Then, $F$ is continuous on $ [a, b]$, differentiable on the open interval (a, b), and $$F' (x) = f (x)\,$$ for all $x$ in $ (a, b)$.
