Quandaries
and Queries 

Hi. I have a set of XY coordinates(say
49 points),I want to find the area enclosed by the curve joining them
and the axes.I do not have an equation
for the curve and I am not able to fit a curve given the points.I use
the trapezoidal rule thank
you 

Hi Prashanth, The trapezoidal rule is the appropriate method to use, however I don't like the way you have written the expression. Y1+Y2/2 is Y1 plus one half of Y2, but you need one half of the sum of Y2 and Y1. The expresion should be Penny
