## Homework Statement

The problem along with its detailed solution are attached.

## Homework Equations

Inequality, infinite summation and improper integral.

## The Attempt at a Solution

I'm following the solution but I can't justify the first (and only) less-than-or-equal sign. Why is that sum less-than-or-equal to that integral?

Also, to be picky, when they say two-decimal place accuracy, shouldn't that mean error <= 5/10^3 instead of error < 5/10^3? Whether I am right or wrong, please tell me why.

Any input would be greatly appreciated!

Thanks in advance!
