## Derivation of relation between $$f$$ and $$T$$

Options for semantic highlighting
intent
A review of the relation between
measure: $$T$$ period
,
symbol: period $$T$$
, and
measure: $$f$$ linear frequency
,
symbol: linear frequency $$f$$
.

The mathematical equation of the relation is

$$T=1/f.$$
intent
Finally, divide both sides of the second equation by
symbol: period $$T$$
to yield the third equation,
$$f=1/T.$$
