Wolfram Alpha is a great website, especially for mathematics. It covers content areas that I have learned in Calculus and Calculus II. Integrals are one of the hardest concepts in Calculus II, and with Wolfram Alpha a student is able to type in the integral or any mathematical problem and view the step-by-step process in order to evaluate it properly. I use it regularly to check my steps integrating integrals for homework assignments outside of class, and a teacher would be able to use this website to instantaneously demonstrate the correct order of events for mathematical equations during class discussions. This is a great educational tool for students and educators.
