Solved by pluggable solver: Distance between two points in two dimensions
The distance (denoted by d) between two points in two dimensions is given by the following formula:
\n" ); document.write( "
\n" ); document.write( " \"d=sqrt%28%28x1-x2%29%5E2+%2B+%28y1-y2%29%5E2%29\"
\n" ); document.write( "
\n" ); document.write( " Thus in our case, the required distance is
\n" ); document.write( " \"d=sqrt%28%28-2-2%29%5E2+%2B+%28-2-4%29%5E2%29=+7.21110255092798+\"
