Function 分析 Knowledge
Critical Points
Critical points are where the derivative is zero or undefined, including local maxima, minima, and inflection points. These points are crucial for understanding function behavior.
Monotonicity
A function is increasing where the derivative is positive and decreasing where the derivative is negative.
Concavity
A function is concave up where the second derivative is positive and concave down where it is negative.
Numerical Differentiation
This 计算器 uses numerical differentiation to approximate derivatives; useful for complex functions that can't be differentiated analytically.
