## Find Extreme and Saddle Points

Solution: Derivative Steps of: ∂/∂x (4x^2 + 8xy + 2y) Multivariable critical point calculator differentiates 4x^2 + 8xy + 2y term by term: The critical points calculator applies the power rule: x^2 goes to 2x. So, the derivative is: 8x. Again, the critical number calculator applies the power rule: x goes to 1. The derivative of 8xy is: 8y.

## Functions Critical Points Calculator

Examples with Detailed Solutions Example 1 Find the critical point(s) of function f defined by f(x , y) = x 2 + y 2. Solution to Example 1: We first find the first order partial derivatives. f x (x,y) = 2x f y (x,y) = 2y We now solve the following
