How does this make sense when k=0?

Oh okay. The lower bound is the index origin and doesn't matter if it is negative?Gene Naden said:The sum is ##3+3+...=3(n+1)##
i.e. one is counting fence posts, not sections of wire.DrClaude said:To summarise,
$$
\sum_{k=a}^{b} c = c (b-a+1)
$$
for constant ##c##.
Summation is a mathematical operation that involves adding up a sequence of numbers or terms.
K=0 refers to the starting point of summation. It means that the sequence starts with 0 and all the numbers or terms after that are added together.
When k=0, the first term in the sequence is 0 and it is added to the remaining terms. This results in the sum of all the terms in the sequence starting from 0.
Yes, when k=0, the summation is simplified and the first term in the sequence is excluded from the sum. This is because adding 0 to a number does not change its value.
Summation with k=0 is useful in simplifying mathematical expressions and solving problems involving sequences. It also allows for a more concise representation of mathematical concepts, making them easier to understand and manipulate.
