Find the first five partial sums of the given series and determine whether the series appears to be convergent or divergent. If it is convergent, find its approximate sum. 3 M 8 (n + 3)(n+ 4) n = 1 - - - The first partial sum is S, =The displacementy (in cm) of an object hung vertically from a spring and allowed to oscillate is given by the equation shown below, where tis the time (in s).
