Venn Diagrams for Sets

Added Aug 13, 2018 by OmarMonteagudo in Mathematics

This widget, by Poodiack, is intended to create a Venn diagram, once that you enter an expression like (A Union B) Intersect (Complement C).

Integrating Products of Sines and Cosines

Added Feb 13, 2013 by Poodiack in Mathematics

Choose your sine and cosine functions for the product and enter your multiples of x. When you hit Submit, WolframAlpha will show how to use product-to-sum formulas to compute the integrals.


Curvature

Added Sep 24, 2012 by Poodiack in Mathematics

Enter three functions of t and a particular t value. The widget will compute the curvature of the curve at the t-value and show the osculating sphere.

Power Series

Added Apr 17, 2012 by Poodiack in Mathematics

Enter a function of x, and a center point a. The widget will compute the power series for your function about a (if possible), and show graphs of the first couple of approximations.


Infinite series

Added Apr 7, 2012 by Poodiack in Mathematics

Enter a starting value for n and the general term of the series. The widget will tell whether the series converges and its sums, a graph of the first few partial sums, and the results of major tests.

Integrals of Powers of Tangents and Secants

Added Feb 17, 2012 by Poodiack in Mathematics

This widget will show how to calculate indefinite integrals of the functions $\tan^m(x) \sec^n(x)$, for $m$ and $n$ integers. Enter your $m$ and $n$ values and then hit "Submit."


Integrals of Powers of Sines and Cosines

Added Feb 17, 2012 by Poodiack in Mathematics

This widget will compute integrals of powers of sine and cosine functions -- integrals of the form $\sin^m(x)\cos^n(x)$. Enter your values for $m$ and $n$ and hit "Submit."

Basic Truth Tables

Added Aug 24, 2010 by Poodiack in Mathematics

Enter two variables and click one of the radio buttons. WolframAlpha will generate a truth table for you for your logical statement.


Distance Formula

Added Aug 24, 2010 by Poodiack in Mathematics

Enter two points (including parentheses). WolframAlpha will compute the distance between the two points using the Distance Formula and display the two points in the Cartesian plane.

Truth Tables for Compound Statements

Added Sep 1, 2010 by Poodiack in Mathematics

You may enter a logical statement, using connectives AND, OR, NOT, and IMPLIES. WolframAlpha will show the symbolic version of your statement, display a truth table for it, and show a Venn Diagram.


Limits

Added Sep 9, 2010 by Poodiack in Mathematics

Enter a function and an x-value. WolframAlpha will compute the limit and show, if possible, a graph and the step-by-step computation.

Venn Diagrams for Sets

Added Sep 30, 2010 by Poodiack in Mathematics

Enter an expression like (A Union B) Intersect (Complement C) to describe a combination of two or three sets and get the notation and Venn diagram. Use parentheses, Union, Intersection, and Complement
