Algebra.Com's Answer #628805 by rothauserc(4718)![]() ![]() You can put this solution on YOUR website! The Van Koch curve is a famous fractal construction \n" ); document.write( ": \n" ); document.write( "First, a straight line(unit length) is divided into three segments. The middle segment is removed and replaced by two segments of equal length that form an equilateral triangle. \n" ); document.write( ": \n" ); document.write( "The above process is repeated for the four segments in the first step. \n" ); document.write( ": \n" ); document.write( "If we start with one line segment for iteration one and look at the the next two iterations we notice the following: \n" ); document.write( "iteration------segment length-----segment number------curve length \n" ); document.write( ":---0-----------------1------------------1------------------1 \n" ); document.write( ":---1----------------1/3-----------------4------------------1.33 \n" ); document.write( ":---2----------------1/9----------------16------------------1.77 \n" ); document.write( ":---3----------------1/27---------------64------------------2.37 \n" ); document.write( ": \n" ); document.write( "The perimeter increases by 4/3 for each iteration, therefore \n" ); document.write( "perimeter = (4/3)^n \n" ); document.write( "This shows that as the number of iterations increases, the curve length(perimeter) tends to infinity while it encloses a finite area \n" ); document.write( ": \n" ); document.write( "Now take a look at the area \n" ); document.write( "We take the first triangle formed on iteration 2 of unit area, then on the next iteration we have four small triangles added. Each triangle is 1/9 the area of the unit triangle. \n" ); document.write( ": \n" ); document.write( "The next iteration produces 16 triangles but each trianlge is 81 times smaller than the unit triangle. \n" ); document.write( ": \n" ); document.write( "iteration-------triangle number-------triangle area-------curve area \n" ); document.write( ":---0------------------0---------------------0----------------0.00 \n" ); document.write( ":---1------------------1---------------------1----------------1.00 \n" ); document.write( ":---2------------------4---------------------0.44444----------1.44444 \n" ); document.write( ":---3------------------16--------------------0.19753----------1.64197 \n" ); document.write( ": \n" ); document.write( "Area = 1 + (4/9)^n where n is number of iteration after the iteration with 1 triangle. \n" ); document.write( ": \n" ); document.write( "Note that this equation converges to 0.8 as n goes to infinity, that is \n" ); document.write( "(4/9) / (1 - (4/9)) = 0.8 \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
