Questions & Answers about Folosești formula pentru a calcula lungimea.
Why does this sentence use the infinitive pentru a calcula instead of the subjunctive ca să calculezi?
Both are grammatically correct ways to express purpose ('in order to calculate'). However, pentru a + infinitive is a bit more formal, technical, or objective. Since this sentence is about math or science, the infinitive sounds very natural, whereas ca să calculezi would sound slightly more conversational.
In the word formula, is the final 'a' the definite article, or just part of the base word?
It is the definite article ('the'). The base unarticulated noun is formulă (ending in -ă). To say 'the formula', the final -ă transforms into -a, giving us formula.
