Enter the text ItemCode in cell L1. The ItemCode is a combination of the inventory code in all uppercase letters, with the item number appended to it. For example, the first ItemCode should be RLXF920569. Use the appropriate function in column L to create this new ItemCode and AutoFill the function down to L20.

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.
