        Expand on the Complex class to make 
          it more useful. Include the following and any other properties you think 
          would be useful : 
          
            Additional constructors such as a default with zero real and imaginary 
              values, a constructor that sets its values to that of a complex 
              object taken as an argument, etc.Provides a static "i" value.Absolute value methodInverse valueMultiplication 
 
Create a similar program as BasicHistApplet1.java 
          in Chapter 3: Tech: Histogram 
          except that it uses the BetterHist 
          class and prints out the mean and standard deviation of a distribution. 
          
 
Create a vector class that includes static methods to carry out dot 
          and cross product operations.
 
Using objects from the vector class in exercise 3, create a matrix 
          class that carries out vector*matrix multiplication.    |  |
