Ax KAMPLE-3Find the differential equation of all circles of radius 5, with their centres on the y-axisUTION :Radius of the circle = 5.Since centre of the circle is on the y-axis then centre C = (0, h).Equation of the required circle is (X - 0)2 + (y - h)2 = (5)2x2 + y2 – 2hy + h2 = 25Differentiating (1) with respect to x, we getdd (x²)+(h)2 =(25)dxddd+ (y)2 – 2h(y) +dxdxdx dxdy dy2x + 2y 2hLetdx dx= 0dydx= y'(x + y)x + yy'hy' = x + y y' = h =y'ubstituting this value in (1), we get(x+yy'), (x+yyl |
