Question

). the mass density of a semicircular wire of radius a varies directly with the distance from the diameter that joins the two endpoints of the wire. ​find the mass equation 人(x,y)

Answer 1

Take x = r*cost and y=r*sint, where t belongs to (-pi/2,pi/2).
and r^2 = x^2+y^2

Answer 2

thanks for the need to be there at an event at
