Test-3 Q.1 (NAT) The number of points at which the solution y(r) of the following differential equation 2ry+6r +(?-4)-0 (0)- 1 d becomes infinite. Q.2 (NAT) Let z*? ++= C be the solution of following exact differential equation (3+) dr + N(a, yjdy - 0 then N(1, 1) equals Q.3 (NAT) Suppose that the solution of the following differential equation 3+y) dr - ry'dy = 0 passing through the points (1,0) and (2, a), then a* equals, where (log 2 = 0.3010)
