Using the gradient vector to find the tangent plane equation

The steps to populate the general equation of the tangent plane are as follows: Plug the values for x0 and y0 into the given function z = f ( x, y) to obtain the value for f ( x0, y0 ). Take the partial

Tangent planes (article)

Find the equation of the tangent plane to the surface defined by the function f(x, y) = sin(2x)cos(3y) at the point (π/3, π/4). A tangent plane to a surface does not always exist at
