Select the correct statement(s) regarding the Address Resolution Protocol (ARP). a. When an IP datagram is received, ARP initially inspects its cache to see if the IP address mapping already exists to a layer 2 MAC address b. ARP broadcasts the received IP address to all stations within the common network if not found within its cache c. ARP maps network addresses to data link layer MAC addresses d. All are correct statements

The value of sin(x) (in radians) can be approximated by the alternating infinite series create a function (prob3_2) that takes inputs of a scalar angle measure (in radians) and the number of approximation terms, n, and estimates sin(x). do not use the sin function in your solution. you may use the factorial function. though this can be done without a loop (more efficiently), your program must use (at least) one. you may find the mod() function useful in solving the problem.
