 # Using Mathematica and Wolfram|Alpha in the Classroom

October 19, 2009 — Wolfram Blog Team

There are lots of things going on at Wolfram Research these days. October 22–24 is our annual International Mathematica User Conference, and October 21 is the first-ever Wolfram|Alpha Homework Day! Homework Day is a groundbreaking, marathon live interactive web event that brings together students, parents, and educators from across the United States to solve their toughest assignments and explore the power of using Wolfram|Alpha for school, college, and beyond. You can read more about it in the Wolfram|Alpha Blog post.

Mathematica and Wolfram|Alpha are great resources for both teachers and students. Using the two together is a good way to explore topics in more depth. This video shows a few examples of how you can utilize Mathematica and Wolfram|Alpha in your own classroom. Posted in: Education
RELATED POSTS ### One Comment    In the video, at 1 min 26 s, the integral shown is int_7.34^3tanx dx = 1.48164 This is wrong! The function tan(x) has a nonintegrable singularity at 3/2Pi ~~ 4.712 inside the integration interval. And even if you consider the integral in a Cauchy sense (you would not tell students about principal values and finite parts anyway), the result is wrong. Compare with the result of Mathematica for this integral: In:= Integrate[Tan[x], {x, 7.34, 3}] Out= -1.12812 + 0. I In:= Integrate[Tan[x], {x, 7.34, 3}, PrincipalValue -> True] Out= -0.699934 + 0. I In:= NIntegrate[Tan[x], {x, 7.34, 3}] Out= 0. In:= NIntegrate[Tan[x], {x, 7.34, 3 Pi/2, 3}, Method -> “PrincipalValue”] Out= -0.699934 Posted by Heis Wernerberg    October 19, 2009 at 7:04 pm
