Enter Function
Examples
Example 1
f(x) = x^3 at x = 3
Derivative = 27
Example 2
f(x) = sin(x) at x = 0
Derivative = 1 in radian mode
Example 3
f(x) = x^2 + 4x at x = -2
Derivative = 0
Estimate the derivative of a function at a point with a simple numerical method. Good for quick checks and school work.
