We compute the partial derivative (by differentiating wrt to specified variable and treating all other variables as constants), and applying the chain rule u_x = (partial u)/(partial x) \ \ \ \= ((1)(12xyy^2)^(2)(2y))/2 \ \ \ \= (y)/(12xyy^2)^(2) And u_y = (partial u)/(partial y) \ \ \ \= ((1)(12xyy^2)^(2)(2x2y))/2 \ \ \ \= (xy)/(12xyy^2)^(2) Next we compute the LHS of the desired expression LHS = x(partial u)/(partial x) y (partial u)/(partial y) \ \ \ \ \ \ \ \ = x((ySOLUTION Explanation Given f(z) = (x 2 y 2) i 2xy g(z) = 2xy i (y 2 – x 2) To check analyticity of a function, we need to check CR equations u x = v y, u y = v x f(z) = (x 2 y 2) i 2xy u = x 2 y 2, v = 2xy u x = 2 x u y = 2 y v x = 2 y v y = 2 x u x = v y but u y ≠ v x Hence, f(z) is not analyticI calculated the integral of $(x y)^2 \,dx$ using the substitution method and got $\frac{1}{3}(xy)^3$ as result Then I applied the distributive property to $(x y)^2$, calculated the integral of $(x^22xyy^2) \,dx$ and I got $\frac{x^3}{3}x^2yxy^2$ as result, which is not equal to $\frac{1}{3}(xy)^3$
Re x2−2xyy2=0 and xy = 9 #permalink , 1804 sandy wrote This is one of the questions you need to pay attention Given x 2 − 2 x y y 2 = 0 or ( x − y) 2 = 0 or x = y Also given that x y = 9, substituting value of x in terms of y or y 2 = 9 Here y can have 2 values 3 and 3 Hence D is correctHow do I solve (X*22xyy*2) dx (y*22xyx*2) dy=0?However this variable involves y and not x, meaning we must differentiate it implicitlyTherefore differentiating 2y^2 would become 4y(dy/dx) Taking a look at the third term, 2xy, we immediately notice that it has both x terms and y terms involved;
