# What is Wolfram alpha: Definition and 25 Discussions

WolframAlpha ( WUUL-frəm-) is a computational knowledge engine or answer engine developed by WolframAlpha LLC, a subsidiary of Wolfram Research. It is an online service that answers factual queries directly by computing the answer from externally sourced "curated data", rather than providing a list of documents or web pages that might contain the answer, as a search engine might.WolframAlpha, which was released on May 18, 2009, is based on Wolfram's earlier flagship product Wolfram Mathematica, a computational platform or toolkit that encompasses computer algebra, symbolic and numerical computation, visualization, and statistics capabilities. Additional data is gathered from both academic and commercial websites such as the CIA's The World Factbook, the United States Geological Survey, a Cornell University Library publication called All About Birds, Chambers Biographical Dictionary, Dow Jones, the Catalogue of Life, CrunchBase, Best Buy, and the FAA.

1. ### I Why is the integral of ##\arcsin(\sin(x))## so divisive?

Initially, I was attempting to find the function which expresses the area under enclosed between the function ##\arcsin(\sin(x))## and the ##x##-axis (so technically I am looking for ##\int_{0}^{x} \arcsin(\sin(t)) dt## specifically, but got caught up on finding the general antiderivative)...

18. ### Analytically Solving Complex Expressions with Wolfram Alpha

I'm noticing wolfram alpha has the amazing ability to analytically solve \sum_{n=1}^{\infty} \frac{1}{n^2 + a^2} Anyone know how to do this, and if it's also possible to deal with higher order guys (like it also can do 1/(n4+a2), but it's a way more complicated expression to the point...

Homework Statement Ok well I had a real nasty equation in which i could not solve. I used wolfram alpha to get out this answer "theta ≈ 0.74559 + 6.28319n for integer n". can someone please tell me what this statement means. do i assume theta in degrees equals 0.74559(180/pi)...

21. ### How to use wolfram alpha to plot frequency response

Can someone please tell me how I can plot the magnitude and phase response of this transfer function on wolfram alpha as I don't have Matlab: H(s) = -(2.1953*10^12)/(66600*((j*ω)^2)+808823539.4*(j*ω)+2.1626*10^12) A link to the output would be very useful also, thanks heaps.
22. ### Worth paying the extra money and upgrading to Wolfram Alpha pro?

Do you guys think it is worth paying the extra money and upgrading to Wolfram Alpha pro?
23. ### Partial Fractions problem not matching Wolfram Alpha

Homework Statement ∫10x-2x2/((x-1)2(x+3)) Solve by partial fractions. The Attempt at a Solution ∫A/(x-1) +B/(x-1)2 + C(x+3) after setting up the partial fractions and multiplying each term by LCD: 10x-2x2= A(x-1)(x+3) + B(x+3) + C(x-1)2 10x-2x2= A(x2+2x-3) +Bx+3B +Cx-C 10x-2x2=...
