What to Focus On
- Derivative is the rate of change of a function.
- Defined using the limit of the difference quotient.
- Notation: $ f'(x) $, $ \frac{dy}{dx} $, $ Df(x) $.
- $ \frac{dy}{dx} $ gives the slope of the tangent to the curve.
- When $ \frac{dy}{dx} = 0 $, the tangent is horizontal.
- When $ \frac{dy}{dx} = \infty $, the tangent is vertical.
- Derivative of any constant is zero.
- Graphically, a constant function has zero slope.
Common Mistakes to Avoid
The derivative of a constant is the constant itself.
You can differentiate each part of a product separately and then multiply the derivatives.
The derivative of 1/x is ln|x|, just like integral.
Memory Tips
Definition of Derivative (First Principle)
Power Rule: d/dx(x^n) = nx^(n-1)
Derivative of Constant is Zero
Sum Rule: (f + g)' = f' + g'
