Johan installs a second SATA hard drive into a 32-bit Windows 7 computer to use to store media files. The drive seems functional and shows up during the POST, but he can't find it in Computer. What tool should he use to make the drive useful?

Which of the following is NOT a default Windows library?

A) Documents B) Music C) Images D) Videos

Write an app that tests whether the examples of the Math class actually produce the indicated results.

``` // Solution: MathTest.cs // Testing the Math class methods. using System; class MathTest { static void Main() { Console.WriteLine($"Math.Abs(23.7) = {Math.Abs(23.7)}"); Console.WriteLine($"Math.Abs(0.0) = {Math.Abs(0.0)}"); Console.WriteLine($"Math.Abs(-23.7) = {Math.Abs(-23.7)}"); Console.WriteLine($"Math.Ceiling(9.2) = {Math.Ceiling(9.2)}"); Console.WriteLine($"Math.Ceiling(-9.8) = {Math.Ceiling(-9.8)}"); Console.WriteLine($"Math.Cos(0.0) = {Math.Cos(0.0)}"); Console.WriteLine($"Math.Exp(1.0) = {Math.Exp(1.0)}"); Console.WriteLine($"Math.Exp(2.0) = {Math.Exp(2.0)}"); Console.WriteLine($"Math.Floor(9.2) = {Math.Floor(9.2)}"); Console.WriteLine($"Math.Floor(-9.8) = {Math.Floor(-9.8)}"); Console.WriteLine($"Math.Log(Math.E) = {Math.Log(Math.E)}"); Console.WriteLine($"Math.Log(Math.E * Math.E) = {Math.Log(Math.E * Math.E)}"); Console.WriteLine($"Math.Max(2.3, 12.7) = {Math.Max(2.3, 12.7)}"); Console.WriteLine($"Math.Max(-2.3, -12.7) = {Math.Max(-2.3, -12.7)}"); Console.WriteLine($"Math.Min(2.3, 12.7) = {Math.Min(2.3, 12.7)}"); Console.WriteLine($"Math.Min(-2.3, -12.7) = {Math.Min(-2.3, -12.7)}"); Console.WriteLine($"Math.Pow(2.0, 7.0) = {Math.Pow(2.0, 7.0)}"); Console.WriteLine($"Math.Pow(9.0, 0.5) = {Math.Pow(9.0, 0.5)}"); Console.WriteLine($"Math.Sin(0.0) = {Math.Sin(0.0)}"); Console.WriteLine($"Math.Sqrt(900.0) = {Math.Sqrt(900.0)}"); Console.WriteLine($"Math.Tan(0.0) = {Math.Tan(0.0)}"); } } ```
