The $\"+1.8+\"$ km is some fraction of the
\n" ); document.write( "entire circumference which is:
\n" ); document.write( " $\"+2%2Api%2A4.5+\"$ km
\n" ); document.write( "----------------
\n" ); document.write( "That fraction is:
\n" ); document.write( " $\"+1.8+%2F+%28+2%2Api%2A4.5+%29+=+.2%2Fpi+\"$
\n" ); document.write( "----------------
\n" ); document.write( "The entire circle is $\"+2%2Api+\"$ radians
\n" ); document.write( " $\"+%28+.2%2Fpi+%29%2A2%2Api+=+.4+\"$
\n" ); document.write( "-----------------
\n" ); document.write( "The skier has gone $\"+.4+\"$ radians from ( 4.5,0 )
\n" ); document.write( "The x-coordinate is:
\n" ); document.write( " $\"+4.5%2Acos%28+.4+%29+=+4.5%2A.921+\"$
\n" ); document.write( " $\"+4.5%2A.921+=+4.145+\"$
\n" ); document.write( "The y-coorinate is:
\n" ); document.write( " $\"+4.5%2Asin%28+.4+%29+=+4.5%2A.389+\"$
\n" ); document.write( " $\"+4.5%2A.389+=+1.752+\"$
\n" ); document.write( "The skier rested at ( 4.145, 1.752 )
\n" ); document.write( "Hope I got it!
\n" ); document.write( "( I believe the skier ends up in the 1st quadrant
\n" ); document.write( "because $\"+pi%2F4+=+.785+\"$ is greater than $\"+.4+\"$
\n" ); document.write( "and that is a 90 degree angle from start ) \n" ); document.write( "

\n" );
