Get stepbystep solutions from expert tutors as fast as 1530 minutes Your first 5 questions are on us!. Explanation We will be differentiating implicitly On the left hand side, we will use the chain rule in regards to the inverse tangent function d dx (arctan(u)) = u' 1 u2 Also, note that the product rule will be used for d dx (x2y) and, eventually, d dx (xy) Differentiating gives. Therefore at (1,2,4), we get wx = −4, wy = 4, so that the tangent plane is w = 4−4(x −1)4(y −2), or w = −4x 4y x x y 2B2 a) zx = = ;.

Calculus questions and answers Problemshow that the function Z=tan^1 (2xy)/ (x^2y^2) satisfies the laplace equationI understand I need to take the partial with respect to X and the partial with respect to y The sum of the partial of x and y should equel zero to make the laplace correct I can't get it to zero outplease help. F(y,x 1,x 2)=0 where the partial derivatives are ∂F/∂x 1 = F x 1, ∂F/∂x 2 = F x 2 and ∂F/∂y = F yThis class of functions are known as implicit functions where F(y,x 1,x 2)=0implicity define y = y(x 1,x 2) What this means is that it is possible (theoretically) to rewrite to get y isolated and expressed as a function of x 1 and x 2.

Calculus Basic Differentiation Rules Implicit Differentiation. Answer (1 of 3) 2xtan ydxsec^2ydy=0 2xdx=sec^2ydy/tan y Integration both sides x^2 = log (tan y) C log (tan y)= C x^2 tan y = e^(Cx^2) tan y = e^Ce^x^2 tan y= ke^x^2 or y = tan^1(ke^x^2) Answer.
Try to make x y ′ a derivative That is achieved by setting v ( u) = y ( u 2), that is, x = u 2, so that v ′ ( u) = 2 y ′ ( u 2) u and v ′ ( u) 2 = 4 x y ′ ( x) 2) Inserted into the equation this gives v ( u) = u v ′ ( u) tan − 1 .
