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.
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)
