This is a nice example brochure template provided by Nicola Talbot using the flowfram package. The flowfram package lets you create frames in a document such that the document content flows from one frame to the next in the order in which they were defined. This is useful for creating posters or magazines or any other form of document that does not conform to the standard one or two column layout. Here we present the sample brochure provided with the flowfram package - it is preloaded into writeLaTeX and ready for real-time editing online. Simply click the screenshot above to create your own brochure and get started!

This problem is an applied optimization problem. The problem is to minimize
the area of the triangle formed by a tangent line to the function y = 1⁄9 x2.

of concern.

A PocketMod is an 8-page booklet made from a single side of paper. This means you can recycle papers that's only been written/printed on one side. See PocketMod.com or this video for instructions to fold the PocketMod.
You can use it to create little books, brochures, handouts, daily planners, or just as a quick notepad or doodling sketchpad.
