There is a parenthesis out of place in the 3rd line.


IIRC, the way to get the CG in a given direction is to take a weighted integral like   Integral (x * f(x)) dx  /  Integral (f(x)) dx

I didn't go through this since I think for a triangle you can draw 3 lines each parallel to a side and 1/3 the distance from that side to the opposite vertex; and they intersect at the Center of Gravity.
