Wolfram Alpha   (also written as Wolfram|Alpha ) is an answer engine  developed by Wolfram Research. It is an online service that answers factual queries directly by computing the answer from structured data, rather than providing a list of documents or web pages that might

contain the answer as a search engine might. It was announced in March 2009 by Stephen Wolfram, and was released to the public on May 15, 2009. Users submit queries and computation requests via a text field. Wolfram Alpha then computes and infers answers and relevant visualizations from a core knowledge base of curated, structured data [1].

   An interesting part of this website is its mathematical and engineering application. Some good examples are:
