How Derivatives Work
A derivative shows how one variable changes when another variable changes.
The standard formula for a derivative is:
f'(x) = lim(h→0) [f(x+h) − f(x)] / h
This formula helps calculate the slope of a curve at a specific point.
For example:
If
f(x) = x²
Then
f'(x) = 2x
This means the rate of change of x² is 2x.
