Each special washing of a pair of overalls removes 80% of the radioactive particles attached to the overalls. Represent, as a sequence of numbers, the percent of the original radioactive particles that remain after each washing.
Problem 15:
Calculate the value of the partial sum for n = 4 and n = 5, and find a formula for sn. (The patterns may be more obvious if you do not simplify each term.)
Problem 16:
In the proof of the Integral Test, we derived an inequality bounding the values of the partial sums between the values of two integrals:

Determine whether the given series Converge Absolutely, Converge Conditionally, or Diverge, and give reasons for your conclusions.
Problem 19:
Find the interval of convergence for the series below. For x in the interval of convergence, find the sum of the series as a function of x. (Hint: You know how to find the sum of a geometric series.)
Problem 20:
Represent the integral as a numerical series:
Use the series representation of these functions to calculate the limits.
Determine how many terms of the Taylor series for f(x) are needed to approximate f to within the specified error on the given interval. (For each function use the center c = 0.)
