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 doesnt mean anything unless you have some knowledge of what calculus is. Lets 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!
