Extraneous solutions are those solutions encountered when solving an equation or system of equations that at first glance appear reasonable, but do not actually satisfy the original conditions of the problem. Extraneous solutions can occur with any...

In mathematics, function is a central idea. Imagine a machine that takes numbered balls from 1 through 26 and labels them with the English alphabet letters A through Z. This machine mimics a mathematical function. A function takes an object from one...

Equations are statements that use numbers and symbols to demonstrate that two groups of mathematical data are equal. The roots or solutions to an equation are numbers that replace the variables (unknown quantities) to make the equation true. The first...

Strong upper level winds forced NASA to abort plans to launch five satellites on a single rocket Friday from the Cape Canaveral Air Force Station, officials said.NASA will attempt to launch the five science satellites again Saturday. The probes are all part of a mission...

Five science satellites blasted off on a single rocket into a golden sunset Saturday on a mission to figure out the source of powerful geomagnetic substorms in the Earth's atmosphere.The launch at 6:01 p.m. from the Cape Canaveral Air Force Station came a day after...
