Need An Answer?

        Need an answer?  Here's help!  John Carter shares the following:  "WolframAlpha Course Assistant has several specialized apps for the iPhone, iPad, or iPod Touch that will solve almost all of your technical problems. Here’s a list of apps currently available:
        "Algebra, Pre-Algebra, Pre-Calculus, Calculus, Multivariate Calculus, Statistics, Music Theory, Astronomy, General Chemistry, Physics I, Physics II, Mechanics of Materials.
        "And more on the way. These apps are a meager $1.99 each (download through the App Store). Hard to believe.
        "But, if you want what all those WolframAlpha Course Assistant apps can do (without the fancy front end that prompts you for input) and answer questions like, “When was Robert Kennedy born?” (the answer is Friday, November 20, 1925) then download WolframAlpha (without specifying Course Assistant) from the App Store ($2.99) and start asking questions.
        "Wait! There’s MORE!
        "You can use WolframAlpha online for FREE! Give it a try!
        There's that word FREE, so you will want to . . . Wait!  John has more to say, "PS: The online version has it all. Check out the example subjects here."
