Given a set of data, Wolfram|Alpha is instantaneously able to compute all manner of descriptive and inferential statistical properties and to produce regression analyses and equation fitting. Wolfram|Alpha computes things.While the use of computations to predict the outcomes of scientific experiments, natural processes, and mathematical operations is by no means new (it has become a ubiquitous tool over the last few hundred years), the ease of use and accessibility of a large, powerful, and ever-expanding collection of such computations provided by Wolfram|Alpha is. Stay on top of important topics and build connections by joining Wolfram Community groups relevant to … Wolfram Natural Language Understanding System. The planets Jupiter and Saturn will pass so close to each other in the sky that, to the unaided eye, they will be difficult to separate. (If yes then how - can you please give some basic example of assigning a value to variable and using it and can you also give an example of using loop statement?) Physics studies features of the universe, ranging from natural to manmade phenomena. Floor[x] gives the greatest integer less than or equal to x. Technology-enabling science of the computational universe. The summation operation can also be indicated using a capital sigma with upper and lower limits written above and below, and the index indicated below. See the Wolfram Language in action.

A Riemann sum is an approximation to the area between a curve and the axis, made by adding together the areas of a set of rectangles. For example, the above sum could be written sum… Array[f, n, r] generates a list using the index origin r. Array[f, n, {a, b}] generates a list using n values from a to b. Examples for Statistics. Maple Version: plot(1/4+sum((cos(n*Pi)-1)/(n*Pi)^2*cos(2*n*Pi*x),n=1..100),x=-1..2); Laplace Transforms. Examples for Chemistry. Wolfram|Alpha also knows a variety of physical formulas and constants. (1) The numbers being summed are called addends, or sometimes summands. Examples for Physics. Knowledge-based, broadly deployed natural language. Wolfram|Alpha uses expertly reviewed curated data, trusted data providers and extensively validated internal algorithms. Calculus, algebra, trigonometry, geometry, number theory, base conversions, statistics. Wolfram|Alpha contains a large volume of data on materials, both manmade and natural, including woods, metals, minerals, plastics and more. Wolfram Community forum discussion about Sum components of a vector in Wolfram|Alpha?. A summation calculation is involved, of the form , where is the width of each rectangle. Array[f, n] generates a list of length n, with elements f[i]. Wolfram Universal Deployment System Instant deployment across cloud, desktop, mobile, and more. The Wolfram Language has full integrated access to the Wolfram|Alpha knowledgebase. Many of these materials have important applications in industry and construction. Statistics is the branch of mathematics involved in the collection, analysis and exposition of data. With Wolfram|Alpha, you can explore data about phenomena in the areas of quantum mechanics, nuclear and particle physics, thermodynamics and Newtonian mechanics. Knowledge-based, broadly deployed natural language. Another thing that Wolfram Alpha can do is compute summations and series; both with known values and with unknown values. The limit of the Riemann sum as approaches zero is the (Riemann) integral of the function. For example, the binomial distribution distributes probability among the possible counts of heads in n flips of a coin that is weighted so that the probability of a single flip landing heads is p : Often using original algorithms developed at Wolfram Research, the Wolfram Language supports highly efficient exact evaluation even for results involving millions of digits. Floor[x, a] gives the greatest multiple of a less than or equal to x. Array[f, {n1, n2, ...}] generates an n1*n2*... array of nested lists, with elements f[i1, i2, ...]. Enter plain English to get instant answers to questions, create and customize graphs and turn static examples into dynamic models. Array[f, {n1, n2, ...}, {r1, r2, ...}] generates a list using the index origins ri (default 1). Let Wolfram|Alpha surprise you with countless fun facts, features and functions, from jokes and riddles to instant image transformations. For example, adding 1, 2, 3, and 4 gives the sum 10, written 1+2+3+4=10. Create instant APIs within the Wolfram Language to implement custom functionality, and immediately deploy in the Wolfram Cloud or in Wolfram Enterprise Private Cloud. Technology-enabling science of the computational universe. Wolfram Science. A sum is the result of an addition. With Wolfram|Alpha, you can explore data about chemical compounds, the reactions they undergo, solubility and chemical graph theory. Hi, I have some questions about abilities and limitations of Wolfram Alpha concerning mathematics: 1) Can I use programming structures (loops, assigning commands)?
