Simplify a summation
WebbI am trying to use Mathematica to simplify a symbolic expression involving Sum. The expression is defined as follows: y = (x - x0)^α Sum[a[n] (x - x0)^n, {n, 0, Infinity}] I am … WebbYou do not need the first $0$ term when summing. Just consider the set $\{1,1,2,2,3,3,\dots\}$ then the sum of first $2n$ terms is $$ S_{2n} = 2 \sum_{i=1}^n i = 2 ( 1 + 2 + \dots + n) = n(n+1) $$ This can be seen by summing $1+2+\dots+n$ with $n+(n …

If polynomial is False, the algorithm computes a rational simplification which minimizes the sum of the total degrees of the numerator and the denominator. WebbLet's first briefly define summation notation. If f(i) represents some expression (function) involving i, then has the following meaning : . The "i=" part underneath the summation sign tells you which number to first plug into the given expression. The number on top of the summation sign tells you the last number to plug into the given expression.

For b), you could start by splitting it up into 2 sums: Note that the second sum on the RHS only needs to start at 1, not 0. As for the second sum, it's geometric, which makes the sum ... Webb24 mars 2024 · A geometric series sum_(k)a_k is a series for which the ratio of each two consecutive terms a_(k+1)/a_k is a constant function of the summation index k. The more general case of the ratio a rational function of the summation index k produces a series called a hypergeometric series. For the simplest case of the ratio a_(k+1)/a_k=r equal to …
WebbF = symsum(f,k) returns the indefinite sum (antidifference) of the series f with respect to the summation index k.The f argument defines the series such that the indefinite sum F satisfies the relation F(k+1) - F(k) = f(k).If you do not specify k, symsum uses the variable determined by symvar as the summation index. If f is a constant, then the default …
