Introduction

The Koch Snowflake The koch snowflake is a fractal that was identified by Helge Von Koch in 1904. It is created by starting with an equilateral triangle, removing the centre third of each side and replacing it with another, smaller equilateral triangle.

Table 1.1: Table of Values For the Koch Snowflake

 Stage Nn Ln Pn An 0 3 1 3 0.433 1 12 4 0.57735 2 48  0.6415 3 192  0.67

Finding the values of N was relatively easy as this was just a process of counting the sides. It was discovered that the Number of sides was

Middle

. The stage 0 was equal to as the side length in stage 0 is equal to 1. Every stage after that was equal to the area of the previous iteration, + (Area of an added triangle) x (Number of added Triangles.).

It should be noted that the graph for Pn is divergent. The perimeter has an infinite value when n approaches infinity.

The graph of An is convergent.  A has a finite value when n approaches infinity.

Generalizations for behaviour within Graphs.

General Formula for Nn:

 n Nn 0 3 1 12 2 48 3 192 N 3(4)n

Conclusion

The general formula for length is one third of the previous length. The general formula is then 1/3n.

Number of sides of the Koch Snowflake Iteration (n) Number of sides (Nn) 0 3 1 12 2 48 3 192 From the table above we can see that there is an increase in the number of sides at every stage by a factor of 4.

((V3)/4), A1= [(V3)/4] + (4/9)0(1/3) ((V3)/4) A2= 10(V3)/27, A2= [(V3)/3] + ((V3)/27), A2= [(V3)/3] + (1/3) (4/9)1 ((V3)/4) A3= 94(V3)/243, A3= [10(V3)/27] + (4(V3)/243), A3= [10(V3)/27] + (1/3) (4/9)2 ((V3)/4) And hence we can see that the general expression is An = An-1 + (1/3)
