The region R is bounded by the curves y=2x, y= 7-x^2 and the y-axis, and its mass density id d(x,y) =xy.
The region R is bounded by the curves y=2x, y= 7-x^2 and the y-axis, and its mass density id d(x,y) =xy. To find the center of gravity of the region you would compute
integral integral R d(x,y) dA = integral ( c to d) integral ( p(x) to q(x) ) d(x,y)dydx, integral (c to d) integral (p(x) to q(x) x d(x,y) dydx, and integral ( c to d) integral ( p(x) to q(x) ) y d(x,y) dydx where,
c= ....
d= ....
p(x) = ....
q(x) = ......
integral (c to d) integral (p(x) to q(x) ) dydx = ....
integral ( c to d) integral ( p(x) to q(x) ) x dydx = ......
integral ( c to d) integral ( p(x) to q(x) ) y dydx = ....
and finally the center of gravity is
x( bar) = ...
y( bar) = ....
