Derivatives and the power rule
A derivative is the slope of a curve at a point. The power rule lets you differentiate any polynomial in one line.
A straight line has the same slope everywhere, but a curve does not. The derivative gives the slope of the curve at each value of — the instantaneous rate of change.
The power rule
- Differentiate a sum term by term.
- A constant term has derivative 0 (a flat line has no slope).
- The derivative of is .
