Topic: error in calculating the curve length

When I calculated the length from 0 to 1 for the function (1-x^2)^0.5 (half circle), I got an error said : An error occurred while evaluating power function. and when I changed the path from 0 to 0.9999999999 I got wrong value returned. (see attached file)

Re: error in calculating the curve length

Graph 4.3 has problems with some corner cases when calculating areas and length of path. Fortunately this has been greatly improved in the beta version of Graph 4.4, which is closed to being released. You can find it at http://padowan.dk/graph/DownloadBeta.php
