Evaluate derivatives, integrals, series approximations, and functional transforms for Critical Point Finder | Multivariable Calculus with complete mathematical derivations.

Understanding Critical Points

In multivariable calculus, critical points are essential for finding local maxima, minima, and saddle points of a function. A critical point occurs where the gradient of the function is zero or undefined. For a function f(x, y), this means solving the system of equations ∂f/∂x = 0 and ∂f/∂y = 0.

How to use this tool:

  • Enter your multivariable function in the 'Function' input field. Use variables like x, y, z, etc., and standard math notation (e.g., x^2 + y^2, sin(x)*cos(y)).
  • Specify the variables in the 'Variables' input field, separated by commas (e.g., x, y).
  • Click the 'Calculate Critical Points' button to find the critical points.
  • The critical points will be displayed in JSON format below. You can copy them for further analysis.
