Aug18 comment $f(x) = x^r$ equaling to $r \cdot x$ when $f$ is cyclic group $G \rightarrow G$ No, the $\cdot$ in $r\cdot x$ is plain old multiplication of integers. This multiplication is not the same as the group operation, which in this case happens to be integer addition. Aug18 comment $f(x) = x^r$ equaling to $r \cdot x$ when $f$ is cyclic group $G \rightarrow G$ The added quote clarifies everything :) When the group operation is addition, $f(x) = rx$ by definition. As Marc notes, the notation is somewhat distasteful. Aug18 answered Find a side of a triangle given other two sides and an angle Aug18 comment $f(x) = x^r$ equaling to $r \cdot x$ when $f$ is cyclic group $G \rightarrow G$ I must be missing something. What do you mean by $r \cdot x$? Is $r$ an element of $G$? Jun25 answered Closest point of line segment without endpoints May12 answered Sum from 0 to n of $n \choose i$?
