From Calculus
Definition at a point
For a function of two variables
Suppose is a real-valued function of two variables
, i.e., the domain of
is a subset of
. We define the partial derivatives as follows:
- Partial derivative with respect to
:
In words, it is the derivative at of the function
.
This partial derivative is also denoted or
.
- Partial derivative with respect to
:
In words, it is the derivative at of the function
.
This partial derivative is also denoted or
.
