Basic Derivatives 436A9D
1. The problem is to list the basic derivative formulas used in calculus.
2. The derivative of a function measures how the function's output changes as its input changes.
3. Here are the fundamental derivative formulas:
- Constant Rule: The derivative of a constant $c$ is zero.
$$\frac{d}{dx}[c] = 0$$
- Power Rule: For any real number $n$, the derivative of $x^n$ is:
$$\frac{d}{dx}[x^n] = nx^{n-1}$$
- Constant Multiple Rule: The derivative of a constant times a function is the constant times the derivative of the function.
$$\frac{d}{dx}[cf(x)] = c\frac{d}{dx}[f(x)]$$
- Sum Rule: The derivative of a sum is the sum of the derivatives.
$$\frac{d}{dx}[f(x) + g(x)] = \frac{d}{dx}[f(x)] + \frac{d}{dx}[g(x)]$$
- Difference Rule: The derivative of a difference is the difference of the derivatives.
$$\frac{d}{dx}[f(x) - g(x)] = \frac{d}{dx}[f(x)] - \frac{d}{dx}[g(x)]$$
- Product Rule: For two functions $f(x)$ and $g(x)$,
$$\frac{d}{dx}[f(x)g(x)] = f'(x)g(x) + f(x)g'(x)$$
- Quotient Rule: For two functions $f(x)$ and $g(x)$,
$$\frac{d}{dx}\left[\frac{f(x)}{g(x)}\right] = \frac{f'(x)g(x) - f(x)g'(x)}{[g(x)]^2}$$
- Chain Rule: For a composite function $f(g(x))$,
$$\frac{d}{dx}[f(g(x))] = f'(g(x)) \cdot g'(x)$$
These formulas are the foundation for finding derivatives of most functions encountered in calculus.
