wolframalpha.com : A very handy online tool I could have used during education Articles / General and Informative articles Date: Aug 28, 2009 - 12:30 AM wolframalpha.com is a very handy site for referring to most of the mathematical solutions and a lot more (in the context of this site, for engineering students). Please do not make it a habit for using this for completing your homework; rather use it as a reference to verify your solutions. The snippet below is (shamelessly) copied from my Aryans' teammate Ameya Kanitkars' blog, "Impressions" Lets look at how it solves some complex high school maths problems - Find LCM (least common multiple of 5, 21, 87) = LCM(5,21,87) = answer Remember quadratic equations ? Lets give it a try, solve 3x^2 + 6x -15 = 35 Moving on - solving linear equations? Lets try to find values of x, y and z from following :7x + 8y - 3z = 80, 2x - 3y + 4z = 35, 6x + 2y + 3z = 50 - here is the answer Finally, (I was lost by this point) - remember chain rule for solving differential equations ? Lets try differentiating (4x + x ^ -5) ^ 1/3 and the answer (Tip: All steps included) Btw, here is complete list of examples. Wish I had this cool tool when I was in school - and the case for not having one, and a smart get away.
