- 1Numerical derivative via central difference: (f(x+h) − f(x−h)) ÷ 2h ≈ 6
Formula
numerical: central difference & Simpson's ruleHow it works
Numerically differentiates a function at a point, or integrates it between two limits. Use x as the variable; ^ for powers.
Example
The derivative of x² at x = 3 is 6; the integral from 3 to 5 is 32.67.
Numerical methods — results are very close approximations, not exact symbolic answers.
