Using the secant method, find the root of f(x) = x^3 – e^(-0.5x) starting with the two points x1 = 0, and x2 = 1. Carry out the first four iterations only. Use 5 significant digits. How to answer this one? Kindly help. Thanks.

4.Let p >0 be the probability that any particular code symbol is erroneously transmitted trough a communication system. Assume than on different symbols errors occur independently of one another. Suppose that with probability q an erroneous symbol is corrected upon receipt. If X denotes the number of correct symbols in a message consisting of a total of n symbols after the correction process has been […]
