An indefinite integral query, expressed once again in English-like language, The negative values of these variables indicate that water is to be poured out instead of being poured in.Ĭalculus functions like integration can also be done. Which by the way gives you the answer to the puzzle: “If you have a five litre bottle and a three litre bottle how can you measure out exactly 11 litres of water.” From the equation, ‘m’ is the number of times you pour in water from the five litre bottle and ‘n’ would be the number of times your pour in water from the three litre bottle. It can even decode diophantine equations such as Polynomials (solve x^3-x^2+x-1), systems of simultaneous equations (solve x+y=0,x-y=1) and equations involving trigonometric and other special functions (solve sin(x)=0.5) can be solved through Wolfram|Alpha. One can also solve equations of various types using this open-source CAS. There is also an equation-editor like “math-input” interface provided for building up complicated expressions by selecting from a palette of templates. Here we entered the expression using the common caret (^) operator for exponentiation. For example, to plot x sin(x) from -5 to 5 we can enter the query:Ī multiplication sign is not required between x and sin(x) and the interval of the plot can be stated in plain English. One can plot 2-D and 3-D functions on Wolfram|Alpha. Yet, once one has developed a feel for its limitations, Wolfram|Alpha is a remarkable tool for a quick calculation or fact check. The natural language processor easily gets confused and the knowledge base is hit and miss. Just like these visions, it turns out Wolfram|Alpha delivers much less than it promises. These ambitions perhaps reflect the maverick personality of Wolfram Research founder Stephen Wolfram, an ex-physicist who has grandiose visions of revolutionising science and computing. Wolfram|Alpha has two ambitious goals: to accept queries in natural English language instead of a programming language with a rigid syntax and to go beyond computer algebra to become a universal knowledge base and computational engine.
#Wolframalpha series license
A basic online-only “Home & Hobby” license for Mathematica that does not allow research or commercial use costs $188/year.įor quite a few years now, Wolfram Research, the makers of Mathematica, have provided a free online alternative in the form of Wolfram|Alpha (). And the commercial systems don’t come cheap at all. The disadvantage of using these systems is that one has to interact with them in a specialised programming language which must be learnt first.
#Wolframalpha series software
Given expressions in terms of algebraic symbols, these computer algebra systems (CAS) can carry out mathematical operations such as differentiation, integration, root finding or simplification and produce a result which is also expressed in the form of symbols.Īt present the most used general purpose CAS is the commercial system Mathematica but there are other commercial and open-source alternatives as well as specialised software for specific branches of mathematics such as number theory or group theory. While the idea of doing mathematics on a computer usually brings up images of number-crunching supercomputers, there also exists a long history of using computers to do mathematics not in terms of numbers but in terms of formulae.
This will be of interest to learners, students, hobbyists, and anyone keen on using tech tools in their daily lives.
