Examples of Use of Mean Value Theorem
Example: $x^3$: Formulation $1$
Let $f$ be the real function defined as:
- $\map f x = x^3$
Let:
- $a = 1$, $b = 2$
Then when $\xi = \sqrt {\dfrac 7 3}$:
- $\map {f'} \xi = \dfrac {\map f b - \map f a} {b - a}$
Example: $x^3$: Formulation $2$
Let $f$ be the real function defined as:
- $\map f x = x^3$
Let:
- $c = 2$, $h = -1$
Then when $\theta = 2 - \sqrt {\dfrac 7 3}$:
- $\map {f'} {c + \theta h} = \dfrac {\map f {c + h} - \map f c} h$
