Now, lets evaluate the same integral using power series. first, find the power series for the function f(x = \frac{32}{x^2+4}. then, integrate it from 0 to 2, and call it s. s should be an infinite series. what are the first few terms of s ?

The weight of a radioactive isotope was 96 grams at the start of an experiment. after one hour, the weight of the isotope was half of its initial weight. after two hours, the weight of the isotope was half of its weight the previous hour. if this pattern continues, which of the following graphs represents the weight of the radioactive isotope over time? a. graph w b. graph x c. graph y d. graph z
