Precalculus on Khan Academy: You may think that precalculus is simply the course you take before calculus. You would be right, of course, but that definition doesn't mean anything unless you have some knowledge of what calculus is. Let's keep it simple, shall we? Calculus is a conceptual framework which provides systematic techniques for solving problems. These problems are appropriately applicable to analytic geometry and algebra. Therefore....precalculus gives you the background for the mathematical concepts, problems, issues and techniques that appear in calculus, including trigonometry, functions, complex numbers, vectors, matrices, and others. There you have it ladies and gentlemen....an introduction to precalculus!

The Antonov 225, once the largest aircraft in the world, the heaviest aircraft ever built and with the largest wingspan, now rests in pieces at the Hostomel airport near Kyiv. It was built as a carrier for the Soviet space craft Buran, it had survived the dissolution of Soviet Union, storage time, repairs and refurbishment, financial difficulties and problems and would serve for many years, carrying huge objects, machines and cargo only to end its career as a victim of battle that took place around it.

War in general isnโt a pleasant place to be, however, it's quite clear that there are some jobs that are simply worse than others. While some soldiers may find themselves in unfortunate positions through direct orders of command, there are other roles that people have willingly volunteered for... and then discovered exactly why it was a terrible, terrible idea. Here are some jobs throughout military history you absolutely do NOT want to volunteer for.
