# Simpson's Rule Input

Posted 11 years ago
 Can someone show me how to enter a Calculus problem using the Simpson's Rule in Wolfram Alpha Pro?  Here is an example:Use Simpson's Rule with n=10 to approximate ?1/x dx from x=1 to 2  I input: ?1/x dx from x=1 to 2; n=10  Wolfram Alpha Pro did not use the Simpsons rule to solve.  The answer is 0.693150 from the answer sheet given to me from my professor.  Wolfram Alpha Pro shows the answer as {log(2), n = 10}  I did input Simpsons Rule in various locations surrounding the problem, but it just shows the definition and history of the rule.  I would appreciate any information.

 Using plain english as you did in your post works:Use Simpson's Rule with n=10 to approximate ?1/x dx from x=1 to 2 http://www.wolframalpha.com/input/?i=Use+Simpson%27s+Rule+with+n%3D10+to+approximate+%E2%88%AB1%2Fx+dx+from+x%3D1+to+2If there are any examples that you tried that did not work, please send in some feedback and the W|A team will check it out.

 Hi. This blog post shows some examples of how you can use different integration methods in Wolfram|Alpha. Included are an example of the MidPoint and Simpson's rule:http://blog.wolframalpha.com/2013/07/11/numerical-methods-integration/
