Homework Statement
What is the difference between the two given equations below? When would you use one or the either?
Homework Equations
## z - z_1 = \frac{∂z}{∂x}(x_1, y_1, z_1)(x - x_1) + \frac{∂z}{∂y}(x_1, y_1, z_1)(y - y_1) ##
## \frac{∂f}{∂x}(x_0, y_0, z_0)(x - x_0) + \frac{∂f}{∂y}(x_0, y_0, z_0)(y - y_0) + \frac{∂f}{∂z}(x_0, y_0, z_0)(z - z_o) ##
The Attempt at a Solution
I am confused because it seems like there are several equations for the tangent plane.
