Final answer:
A first partial derivative calculator is used to find the partial derivative of a function with respect to the first and second variables.
Step-by-step explanation:
A first partial derivative calculator is used to find the partial derivative of a function with respect to the:
- First variable
- Second variable
- Both variables
- Constant term
The first partial derivative with respect to the first variable is found by taking the derivative of the function with respect to the first variable, treating all other variables as constants. Similarly, the second partial derivative with respect to the second variable is found by taking the derivative of the function with respect to the second variable, treating all other variables as constants. If the function has multiple variables, both partial derivatives can be calculated to determine how the function changes with respect to each variable individually.
