Find the equation of the tangent plane to the graph of f(x, y) = In (11x2 - 832 ) at the point (1, 1). (Use symbolic notation and fractions where needed. Enter your answer using x-, y-, z-coordinates.) the equation:Let f(x,y) = ;:jl . Use the Linear Approximation at an appropriate point (a, b) to estimate f(5.04,1.91). (Use decimal notation. Give your answer to two decimal places.) Estimate f(3.05,3.93) assuming that f(3.4) =3, /x(3,4) =017, f,3.4)=-038 (Use decimal notation. Give your answer to three decimal places.)
