Method 1 (Naive : O(n 2)) The idea is to run two loops to consider all possible pairs and keep track of maximum value of expression (arr[i]-i)-(arr[j]-j). Textbook Solutions 7836. This is not surprising, since adding a finite value to an infinite value should result in an infinite value. The answer is 1000 1+(.09)(3) = 1000 1.27 = $787.40. Learning Objective: 09-02 The future value is based on the number of periods over which the funds are to be compounded at a given interest rate. When you square the square root of a number, the answer is simply that number, so i^2 = -1. i^3 is i^2 times i, so it's the negative square root of -1. i^3 = -√(-1) i^4 is i^2 times i^2, and since we know i^2 = -1, you simply multiply -1 by … Evaluate the following. Worksheets("Sheet1").Range("A1").Value = 3.14159 This example loops on cells A1:D10 on Sheet1 of the active workbook. The square of an imaginary number bi is −b 2.For example, 5i is an imaginary number, and its square is −25.By definition, zero is considered to be both real and imaginary.
