Derivative Rules The Derivativetells us the slope of a function at any point. There are ruleswe can follow to find many derivatives. For example: The slope of a constantvalue (like 3) is always 0 The slope of a linelike 2x is 2, or 3x is 3 etc and so on.

The chain rule states that if f(x) and g(x) are both differentiable functions and the composite function defined as F=f(g(x)), then F is ...

The Derivative tells us the slope of a function at any point. There are rules we can follow to find many derivatives. For example: The slope of a constant value (like 3) is always 0; The slope of a line like 2x is 2, or 3x is 3 etc; and so on. Here are useful rules to help you work out the derivatives of many functions (with examples below).

• Chain Rule: h(x)=f(g(x))thenh0(x)=f0(g(x))g0(x) • Trig Derivatives: – f(x)=sin(x)thenf0(x)=cos(x) – f(x)=cos(x)thenf0(x)=−sin(x) – f(x)=tan(x)thenf0(x)=sec2(x) – f(x)=sec(x)thenf0(x)=sec(x)tan(x) – f(x)=cot(x)thenf0(x)=−csc2(x) – f(x)=csc(x)thenf0(x)=−csc(x)cot(x) • Exponential Derivatives – f(x)=ax thenf0(x)=ln(a)ax

Derivative examples; Derivative definition. The derivative of a function is the ratio of the difference of function value f(x) at points x+Δx and x with Δx, when Δx is infinitesimally small. The derivative is the function slope or slope of the tangent line at point x. Second derivative. The second derivative is given by: Or simply derive the first derivative: Nth derivative. The nth derivative is calculated by deriving f(x) n times.

Derivative rules ; Derivative sum rule. ( a f (x) + bg(x) ) ' = a f ' (x) + bg' (x) ; Derivative product rule. ( f (x) ∙ g(x) ) ' = f ' (x) g(x) + f (x) g' (x).

This shows that through different derivative rules, we can easily find the derivative of polynomials such as f ( x) = 4 x 3 – 5 x 2 + 6 x – 1. In fact, we have f ′ ( x) = 12 x 2 − 10 x + 6. Example 2 Find the derivative of the function, g ( x) = sin x 4 – 5 x 5 + x. Solution

The following diagram gives the basic derivative rules that you may find useful: Constant Rule, Constant Multiple Rule, Power Rule, Sum Rule, Difference Rule, Product Rule, Quotient Rule, and Chain Rule. Scroll down the page for more examples, solutions, and Derivative Rules.

• Constant Multiple Rule: g(x)=c·f(x)theng0(x)=c·f0(x) • Power Rule: f(x)=x n thenf 0 (x)=nx n−1 • Sum and Difference Rule: h(x)=f(x)±g(x)thenh 0 (x)=f 0 (x)±g 0 (x)

56 Chapter 3 Rules for Finding Derivatives EXAMPLE 3.1.1 Find the derivative of f(x) = x3. d dx x3 = lim ∆x→0 (x+∆x)3 − x3 ∆x. = lim ∆x→0 x3 +3x2∆x+ 3x∆x2 + ∆x3 −x3 ∆x. = lim ∆x→0 3x2∆x+3x∆x2 +∆x3 ∆x. = lim ∆x→0 3x2 +3x∆x+ ∆x2 = 3x2. The general case is really not much harder as long as we don’t try to do too much.

The first graph shows g(x) = 3x2 and Figure 3.3.1: The derivative of g(x) is 3 times the derivative of f(x).

Rules for Finding Derivatives It is tedious to compute a limit every time we need to know the derivative of a function. Fortunately, we can develop a small collection of examples and rules that allow us to compute the derivative of almost any function we are likely to encounter.
