Find N degree polynomial from N+1 points Which by definition means they're all the same Does this mean that given any set of n+1 points, there exists a polynomial of degree n that passes through all of them? Or does this only work if the points have a uniformly increasing x value (in this case 1) If so, how can I construct such a polynomial?
Intuition for volume of a simplex being $\\frac 1{n!}$ $\frac{1}{n!}$, but I am intuitively struggling to see why I have seen proofs for this and am convinced, but I can't help but think there must be a slicker or more intuitive argument for why this is so than what I have already seen
Simplify K! (K+1)! - Mathematics Stack Exchange Pretend K=3 That means (K+1)= 4 This means you'd be dividing 3*2*1 by 4*3*2*1 Consider how you'd cancel out multiples by dividing them Like how (2 (5+x)) 2 would just equal 5+x Following that idea we'd pretty much be able to cancel out every number in the numerator, so long as its also in the denominator This would end up canceling every number except for 4 which equals (K+1) Essentially
