5F   Thursday JP  

JP:    Project for your JP journal:              Buffon's Needles for Pi

You are going to estimate pi by doing a needle drop onto a sheet with parallel lines (I will demonstrate this on Tuesday). 

   Pi = 2 times the number of drops divided by the number of hits

An example of the mathematics of a needle drop is shown below.

In your JP file, complete the following information for 3 needle drop experiments:

Needle Drop  # Drops Number of Hits

Mathematics to Find Pi  (approximately)
    1      
    2      
    3      

 

Example for finding Pi

Pi = 2*100/62 = 200/62 = 3.22

        Save this in your JP journal summary for the week...due Friday.
