View source for Delta derivative at right-scattered

==Theorem==
Let $\mathbb{T}$ be a [[time scale]]. Let $f \colon \mathbb{T} \rightarrow \mathbb{R}$ be [[continuous]] and [[right-scattered]] at $t \in \mathbb{T}$. Then
$$f^{\Delta}(t)=\dfrac{f(\sigma(t))-f(t)}{\mu(t)},$$
where $f^{\Delta}$ denotes the [[delta derivative]], $\sigma$ denotes the [[forward jump]], and $\mu$ denotes the [[forward graininess]].
