DO NOT TURN IN

 

Practice problem 2A:  Using the function gaussvar found in ranlib.f, write a calling program to compute the average values of x, x2, and x4.  The answers should be around 0, 1, and 3.

 

Practice problem 2B: The function ran3 found in ranlib.f generates uniformly distributed random numbers between 0 and 1.  Using it, creating a new function which generates uniformly distributed random numbers between -1 and 1. Nothing fancy is needed to do this.

 

Practice problem 2C: Using the new function you wrote in 2B above, compute <x>, <x2>, and <x4>. You should be able to calculate with pencil and paper the exact result, and with sufficient number of points your program should get close to that exact answer.
