(b) Graph of the first ten partial sums.

$\"\"$

(c)

The points alternate sides of the horizontal line $\"\"$ that represents the sum of the series.The distance between the successive points and the line decrease.

$\"\"$

(d)

The distance in part $\"\"$ is always less than the magnitude of the next term of the series.
