how to set lift and drag coefficients in force mon
 
I am simulating an airfoil for finding lift and drag coefficients. As per fluent tutorial for lift coefficient the value to be set in Force moniter is x = sin(theta), y = cos(theta).

But Cornell university tutorial says to use x = -sin(theta), y = cos(theta). I am confused. Which one is correct. Can any one help. Thanks.
