Study Notes
Numerical Differentiation
- The small number 'h' represents a small increment added to the variable 'x' to approximate the change in the function's value.
- It is used to compute the difference quotient, which approximates the derivative.
Slope of the Secant Line
- The slope of the secant line through the points ((x, f(x))) and ((x + h, f(x + h))) is given by the formula (\frac{f(x + h) - f(x)}{h}).
- This slope estimates the average rate of change of the function (f) over the interval ([x, x + h]).
Slope as 'h' Approaches Zero
- As 'h' approaches zero, the slope of the secant line approaches the slope of the tangent line at point (x).
- This limit is referred to as the derivative of the function at that point.
True Derivative of (f) at (x)
- The true derivative of (f) at (x) is denoted as (f'(x)).
- It provides the instantaneous rate of change of the function at the specific point (x).
Newton's Difference Quotient
- Another name for Newton's difference quotient is the "first difference."
- It is used in numerical differentiation to approximate derivatives, particularly in Newton's method for root-finding.
