Anyways, in both cases, the two constants A and B must remain You cannot eliminate one at this stage of the calculus Second At the end, it is not correct to add a new constant D, because (df/dx)/f is not an integral Finally, you will obtain an expression y (x) with, into it, one parameter on the form C= (A/B), or C= (B/A), which can beX2y2!2 0 zdzdydx $ x2 y2 =!π/2 0!2 0 r!2/2 0 zrdzdrdθ r = 2π 5 The region or solid is in the Þrst octant between the paraboloid and the cylinder as indicated in the picture above It is the set of all points (x, y,z) satisfying the three inequalities 0 ≤ z ≤ x2 y2 2,0≤ y ≤ √ 4 − x2,and0≤ x ≤ 2 The equation is invariant under the above scaling whenever α = ± β It means, It suggests the change of variables u ≡ y x y = u x Namely, You could treat 2 x y y ′ = x 2 − y 2 as homogeneous (after a bit of algebra) But this is an exact equation You have P = − x 2 y 2 and Q = 2 x y Notice that P y = 2 y = Q x

JustAnswer is not responsible for PostsComplete Factor x^2y^2 Shell, There is a great deal of pattern recognition in factoring, by that I mean looking at an expression and seeing patterns you have seen before and recognizing how to factor them This is true of the "difference of squares" you sent us, x 2 y 2 Once you think you know the factors you can check by multiplicationIf x=0 in the original equation (x 2 y 2) 2 = 2x 22y 2, then (0y 2) 2 = 02y 2, y 4 2y 2 = 0 , y 2 ( y 2 1 ) = 0 , and y=0 Note, however, if x=0 and y=0 are substituted into Equation 1, we get the indeterminate form " 0/0 " Is y'=0 at the point (0, 0) , ie, does y'(0, 0) = 0 ?
