   Nov 16, 2022 · In this section formally define just what a tangent plane to a surface is and how we use partial derivatives to find the equations of tangent planes to surfaces that can be written as z=f(x,y). We will also see how tangent planes can be thought of as a linear approximation to the surface at a given point.

   Jan 16, 2023 · Since the derivative \(\dfrac{dy}{dx}\) of a function \(y = f (x)\) is used to find the tangent line to the graph of \(f\) (which is a curve in \(\mathbb{R}^2\)), you might expect that partial derivatives can be used to define a tangent plane to the graph of a surface \(z = f (x, y)\). This indeed turns out to be the case.

   Nov 16, 2022 · To see this let’s start with the equation \(z = f\left( {x,y} \right)\) and we want to find the tangent plane to the surface given by \(z = f\left( {x,y} \right)\) at the point \(\left( {{x_0},{y_0},{z_0}} \right)\) where \({z_0} = f\left( {{x_0},{y_0}} \right)\).

   Dec 29, 2020 · Derivatives and tangent lines go hand-in-hand. Given y = f(x), the line tangent to the graph of f at x = x0 is the line through (x0, f(x0)) with slope f ′ (x0); that is, the slope of the tangent line is the instantaneous rate of change of f at x0.

   How do you find the tangent plane of a surface?

   • Suppose that we want an equation of the tangent plane T to the surface z = f(x, y) at a point (a, b, f(a, b)). Let Lx and Ly be the tangent lines to the traces of the surface in the planes y = b and x = a, respectively (as in Figure 2.3.2), and suppose that the conditions for T to exist do hold. Then the equation for T is

   How do you know if a line is tangent?

   • However, in three-dimensional space, many lines can be tangent to a given point. If these lines lie in the same plane, they determine the tangent plane at that point. A more intuitive way to think of a tangent plane is to assume the surface is smooth at that point (no corners).

   How many lines can be tangent to a curve at a point?

   • Intuitively, it seems clear that, in a plane, only one line can be tangent to a curve at a point. However, in three-dimensional space, many lines can be tangent to a given point. If these lines lie in the same plane, they determine the tangent plane at that point.

   Which tangent line has a slope of 0?

   • Note that this point comes at the top of a "hill,'' and therefore every tangent line through this point will have a "slope'' of 0. That is, consider any curve on the surface that goes through this point. Each curve will have a relative maximum at this point, hence its tangent line will have a slope of 0.
