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!

Nice vid, very well explained. Thanks khan
Nice explain
We need IMO Solution in videos
The International Mathematical Olympiad (IMO)
The equation for the geometric series should be 4008(10^-4)^n and not 0.4008(10^-4)^n
why though. then youll get 1 as your a0 term
but the fraction ,unfortunately ,in the end , did not give us the repetitive number 0,4008 .
could someone explain it to me?
@@radiob5623 the calculator gives me a big fraction but when I try to use decimal mode it wouldn't work .
