Simplifying summations

WebbSummand is a function of two indices: b = Sum [x [r] Sum [ (x [i] - x [r])^2, {i, n}], {r, n}]; mySimplify [b] /. sRules (* -> -2 s [1]^2 + 2 n s [2] *) Double sum: c = Sum [ (x [i] - x [r])^2, {r, n}, {i, n}]; mySimplify [c] /. sRules (* -> -2 s [1]^2 + 2 n s [2] *) WebbUse the binomial theorem, which states: ∑ n = 0 k a n b k − n k! n! ( k − n)! = ( a + b) k. Use a = b = 1, that is where the 2 k comes from. The -1 is because the theorem includes the …

WebbHow do i derive the formula for summation? Sum from k to n i = [ (n-k+1) (n+k)]/2 • ( 6 votes) Ian Pulizzotto 3 years ago Another way to derive this formula is to let S = Sum from k to n of i, write this sum in two ways, add the equations, and finally divide both sides by 2. We … WebbThen, use summation identities to simplify your equations. For example, we can represent the first loop using this summation. This simplifies to just 'n', as per Gauss's sum identity.
