# Using Wolfram|Alpha in the Classroom

Wolfram|Alpha is a free online computational knowledge engine that generates answers to questions in real time by doing computations on its own vast internal knowledge base. Our long-term goal is to make all systematic knowledge immediately computable and accessible to everyone. This can be valuable to educators in many ways.

### Gather information on a general concept

Derivatives » |
Maps » |
Stars » |
Animals »

### Research details on specific topics

sinx » | AAGCTAGCTAGC » | H2O » | USA »

### Use it in lesson planning

### Create visual aids for presentations or

handouts, including images and graphs

Michael » |
plot x^2+5 and x^3 »

tetrahedron » |
chart US population »

buckyball 3D structure »

### Show steps to math problems

solve 3x+4= 5x +7 » |
derivative of cosx * sinx »

limit of x^2/(3-x) as x -> 0 »

For more ideas, see the Step-by-Step Math post on the Wolfram|Alpha Blog.
