In mathematics, the Cauchy–Hadamard theorem is a result in complex analysis named after the French mathematicians Augustin Louis Cauchy and Jacques Hadamard, describing the radius of convergence of a power series. It was published in 1821 by Cauchy, [1] but remained relatively unknown until Hadamard …The internet and television have finally converged. The internet and television have finally converged. On Tuesday, Jan. 27, Dish Network will begin rolling out the first live tele...I'm working on a problem that asks me to determine the convergence center, radius, and interval of the following power series: $$\sum^{\infty }_{k=2} \left( k+3\right)^{2} \left( 2x-3\right)^{k}$$ Here's what I've attempted so far: To find the convergence center, I set $$(2x-3)^k = 0$$ and solved for x. This gives me x = 3/2, …. Score based generative modeling through stochastic differential equations
