Expert Solution
Step 1

What is Error:

Error is the difference between a genuine value and an estimate, or approximate, representation of that value in practical mathematics. The discrepancy between the mean of the complete population and the mean of a sample taken from that population is a frequent example in statistics. When an infinite series is ignored for all but a small number of terms, a truncation error occurs.

To Determine:

We determine the value of e-6 using two different infinite series taking first term. Then, we determine the approximate and true relative error by comparing the approximate values with true value of e-6 given as  0.002478752177.
