Let f (x) = cos x and g(x) = sin x. Find the center of gravity (x, y) of the region between the graphs of f and g on [0, 𝜋/2].

Question

(x, y)=

Answer 1

(1.5707963267949, 0)

Answer 2

nope

Answer 3

x = y = 4r/3π =
so it's (4/(3π) , 4/(3π))

CLEARLY not at (π/2,0) which lies on the x-axis, and isn't even inside the circle!
