**Wyzant: Area Under a Curve**

How much space is left under the bed? How much area is under the trajectory of the red angry bird? You can calculate these areas using integrals.

**Simple Integration with Polar Coordinates**

We don't mean integrating the polar bear population into the Antarctic Circle. Learn how to do some simple integration using polar coordinates.

**Integrating with Polar Coordinates**

Here's a more link with a few more complicated examples of integration with polar coordinates. It turns out that the penguins wanted friends, after all.

**Arc Length**

You know how to calculate the area under the angry bird's trajectory in space. Now you can figure out just how far he had to go to take out that greedy pig.

**Finding Arc Length**

How far do you throw that marshmallow to get it to your friend's mouth? This video will teach you. With some practice, you'll have a neat parlor trick.

**Volume of Solids**

Do you get the waffle cone or the regular cone? The answer is simple: the one that holds more ice cream. Make out at the soda shop by learning how to find these volumes.

### Games and Tools

**Visualization Tools for Integration of Solids**

Make a bundt cake with a parabola. Make an ice cream cone with a triangle. See how to do it here.

**Visualizing Disk and Washer Integration**

We can also easily make Frisbees with integration. You can visualize how to revolve simple geometries around the origin to make simple geometries with this tool.

**Visualizing Solids**

The Egyptians and the Mayans made the pyramids. It'd probably have been much easier if they had this tool to see what they were doing.

**Visualizing More Solids**

If you can dream up a shape and write an equation for it, you can revolve it around an axis using integration to make an even neater geometry. The next time an art major says you can't do what they do, show off with this link.
