Write an equivalent series with the index of summation beginning at n = 1. ∞ (−1)n + 1(n + 1)xn n = 0

kkurt [141]

Looks like the starting series is

$\displaystyle\sum_{n=0}^\infty\left((-1)^n+1\right)(n+1)x^n$

Note the degree of the first few terms in the series, for $n=0,1,2$ , are $x^0,x^1,x^2$ , and so on.

So if the series were to start at $n=1$ , we would need to preserve that pattern, and we do that by replacing $n$ with $n-1$ :

$\displaystyle\sum_{n=1}^\infty\left((-1)^{n-1}+1\right)(n-1+1)x^{n-1}$

Simplifying a bit, we end up with

$\displaystyle\sum_{n=1}^\infty\left(1-(-1)^n\right)nx^{n-1}$

Suppose why varies directly with X. Write a variation equation that relates x and y

diamong [38]

Answer:

$x = y - 6.4$

Steps :

1. Create an equation

If x-4=0 and y-10.4=0, then x - 4 = y - 10.4

$x - 4 = y - 10.4$

2. Isolate variable X by adding 4 to both sides

$x = y - 6.4$

3. (Optional) Check Answer by plugging given values into the equation

$(4) = (10.4) - 6.4$

4 = 4 is a true statement
