Numerical Derivative Calculator
Evaluate the first and second derivative of any function f(x) at a point using high-accuracy finite differences.
How to use the Numerical Derivative Calculator
- Enter or select: f(x), At x =.
- The results (f(xβ), fβ²(xβ), fβ³(xβ), Tangent line) are calculated instantly as you type.
- Use βCopy linkβ to share the calculation with the same input values.
Formula
- fβ²(x) β [βf(x+2h) + 8f(x+h) β 8f(xβh) + f(xβ2h)] / 12h
