1. determine if the given differential equation is separable, linear or exact it may hint: when checking for exact, you should parable, linear or exact (it may be all three). ot exact, you should re-write to the midr+ n a y form. a) 3x? y + + (x3 + zey - 2y) - 0 b) + (1+y)} = 0 c) a = 2xy + 3x? ex? d) e*(y-2) + (1+emale = 0 ) 2 - 43 + y sin z = (3xy2 + 2y cos oldy
