Apr 17, 2025 · The derivation can be found here in this site. We want to show that $$\\delta(x) = \\frac{1}{2\\pi}\\int_{-\\infty}^{\\infty} e^{ikx}dk$$ by performing the integral ...

Dec 21, 2023 · What are the rules for evaluating an indefinite integral by by expanding the integrand in power series and integrating the power series term by term. Ask Question Asked 2 years, 3 months …

I'm trying to evaluate the following definite integral but am unsure how to handle the absolute value efficiently over the given interval. Any hints on finding the points where the expression inside

Operation precedence is not a needed concept. One might argue that the correct precedence is none at all. Just write things in Polish (prefix), or Reverse Polish (postfix) notation. It's not like you'd stop …

I am trying to evaluate the integral $$\int \frac {1} {1+x^4} \mathrm dx.$$ The integrand $\frac {1} {1+x^4}$ is a rational function (quotient of two polynomials), so I could solve the integral if I ...

Apr 27, 2024 · This result can be obtained using double integrals with polar coordinates, among other things, but I'm particularly interested in evaluating this integral using power series.

Dec 7, 2018 · I see now how I can go about evaluating the limit itself although I still find the concept a little bit vague, as in considering a specific order for the expansion and then applying it for all the …

Nov 17, 2019 · I am hoping someone can help me check my work here. I need to evaluate this limit: $$\lim_ {x \to \pi/2} (\sin x)^ {\tan x}$$ Since $\sin x$ and $\tan x$ are continuous functions, using the …

Oct 13, 2015 · When evaluating a limit expression, how do we know whether to evaluate the Right hand limit and left hand limit separately OR evaluate the "two-sided-limit"?
