Consider the series [infinity]
∑ (-1)^n (x+1)^n/ (n+1)!
n=0

a. Find the series' radius and interval of convergence.
b. For what values of x does the series converge absolutely?
c. For what values of x does the series converge coditionally?

(a) If

then by the ratio test, the series converges for all x, since

so the series radius of convergence is ∞ and the interval of convergence is (-∞, ∞).

(b) The series converges everywhere absolutely, because the ratio test for

also shows the radius of convergence is ∞.

(c) The series converges absolutely, so conditional convergence is moot.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

translate k to n and reflect across the line containing jk.
