e-e(n+1) Show that ex 1-et 0.16. Prove equation (0.13) is true: If a and r < 1 are real-valued constants, then art x=0 a Just take the limit: lim S. (Refer to Exercise 0.14.) 11+00 Why can't equation (0.13) be true if [r] >1? 0.17. Show that for any real-valued constant p: (") p* (1 - p)=1 Hint: See equation (0.15). 1.1. Provide one counterexample (you only need one) to show that it is not always true that = For example, let n = 3, and choose actual numbers (values) for x1, x2 and x3 such that the two sides of the equation are not equal.
