==section input Find distance between 2 points with the coordinates: x1 *[input x1=0] y1 *[input y1=0] x2 *[input x2=1] y2 *[input y2=1] You may enter negative numbers for negative coordinates. ==section solution perl my $soln = sqrt(($x2-$x1)*($x2-$x1)+ ($y2-$y1)*($y2-$y1)); print "The distance (d) between two points is given by the following formula: {{{d=sqrt((x2-x1)^2 + (y2-y1)^2)}}} Thus in our case, the required distance is {{{d=sqrt(($x2-$x1)^2 + ($y2-$y1)^2)= $soln }}} For more on this concept, refer to <A HREF=Distance_formula.wikipedia>Distance formula</A>. "; ==section output soln, ==section check x1=-2 y1=-6 x2=-7 y2=1 soln,= x1=-2 y1=-6 x2=-7 y2=1 soln,= x1=0 y1=0 x2=3 y2=4 soln=5
