A step by step partial derivatives calculator for functions in two variables is presented. You may first want to review the
rules of differentiation of functions and the formulas for derivatives.

## Use of the Partial Derivative Calculator

1 - Enter and edit function \( f(x,y) \) in two variables, x and y, and click "Enter Function".

The five operators used are: + (plus) , - (minus), / (division) , ^ (power) and * (multiplication). (example: f(x,y) = x/y - 2*x + 2*x*y).(more notes on editing functions are located below). The ln(x) (natural log) function is entered as log(x).

2 - Click "Calculate Derivative" to obain the partial derivatives in two steps each. The first step using the rules of derivatives and the second is the simplified form of the derivative.
Notes: In editing functions, use the following:

1 - The five operators used are: + (plus) , - (minus), / (division) , ^ (power) and * (multiplication). (example: f(x,y) = x/y - 2*x + 2*x*y)

2 - The function square root function is written as (sqrt). (example: sqrt(x^2-1)

3 - The exponential function is written as (exp). (Example: exp(x+2) )

4 - The ln (natural log) function is written as (log). (Example: log(2x+3) )

5 - The absolute value function is not supported directly but you can transform an absolute value function into a square root function as follows: | u | = sqrt(u^2)
