Derivative of Implicit Multivariable Function – Taylor series up to second order – Exercise 4768

Exercise

The equation

(z+1)e^{xy+z}=1

Defines the implicit function

z=z(x,y)

Around the origin (0,0,0)

1. Calculate its partial derivatives

z'_x(0,0), z'_y(0,0), z'_{xx}(0,0), z'_{xy}(0,0), z'_{yy}(0,0)

2. Find its Taylor series up to second order around the origin.

Final Answer

z(x,y)\approx -\frac{xy}{2}
