Cultural Tip
In Brazilian Portuguese, the polite imperative uses 'defina' (você) rather than 'define' (tu). The form 'Define' is common in Portugal or in informal speech among friends. Also, Portuguese speakers often treat 'frequência' and 'quantidade' as concrete parameters, so adding the article 'a' signals that you are talking about a specific, already‑known set of data.
