Is addition and one when it is subtraction x^ {2}yxy^ {2}=43 x 2 y x y 2 = 4 3 Subtract 43Using the binomial coefficients, the above formula can be written as (x y)n = (n 0)xn (n 1)xn − 1y (n 2)xn − 2y2 (n k)xn − kyk (n n)yn where (n k) = n!Figure 1572 Double change of variable At this point we are twothirds done with the task we know the r θ limits of integration, and we can easily convert the function to the new variables √x2 y2 = √r2cos2θ r2sin2θ = r√cos2θ sin2θ = r The final, and most difficult, task is to figure out what replaces dxdy

Y ˙ Y But Var(X) = ˙2 X and Var( Y) = Var(Y) = ˙2 Y, so that equals 2 2Cov X ˙ X;X^2 y^2 = x^2 2xy y^2 2xy = (x y)^2 2xy x^2 y^2 = x^2 2xy y^2 2xy = (x y)^2 2xy ∴ (i) x^2 y^2 = (x y)^2 2xy (ii) x^2 y^2 = (x y)^2 2xyObviously $xb yb = b(x y)$ If you see that, your problem is identical with the replacement $b = (x y)$ As a side issue, derivations like this are generally easier to accomplish going from complicatedtosimplified form Start with $(x y)^2$ and simplify it;

( x y z ) 2 = x 2 y 2 z 2 2(x)(y) 2(y)(z) 2(z)(x) = x 2 y 2 z 2 2xy 2yz 2zxThe paraboloid x = y z is shown in cyan and purple In the image the paraboloids are seen to intersect along the z = 0 axis If the paraboloids are extended, they should also be seen to intersect along the lines z = 1, y = x;So, excluding that special case, let X,Y denote the absolute values of x and y, and observe that if x and y have opposite signs the expression for N can be written in the form X^2 Y^2 K N = K XY1 which shows that x^2 y^2 must be less than K in order for N to exceed K

The example below demonstrates how the Quadratic Formula is sometimes used to help in solving, and shows how involved your computations might get Solve the system x 2 – xy y 2 = 21 x 2 2xy – 8y 2 = 0 This system represents an ellipse and a set of straight linesCos(xy)/2 । Trigonometry Formula Proofs #HowtoproveCosxCosy=2Cos(x y)/2×Cos(xy)/2 । #TrigonometryFormulaProofsExamples (n 0) = n!

Of course, (b) is the complete factorization, (a) is not Comparing the results in (a) and (b), we can get x 4 x 2 y 2 y 4 = (x 2 xy y 2)(x 2 –xy y 2) Further investigationSOLUTION 15 Since the equation x 2 xy y 2 = 3 represents an ellipse, the largest and smallest values of y will occur at the highest and lowest points of the ellipse This is where tangent lines to the graph are horizontal, ie, where the first derivative y'=0This is the kind of problem that algebra exists to answer mathx^2 = y^2/math mathx^2 y^2 = 0/math math(xy)(xy) = 0/math mathxy = 0 \text{ or } xy
