Describe the following set in Roster form:
The set of all letters in the word 'Trigonometry'
Advertisements
उत्तर
The word 'Trigonometry' contains the following letters:
T, r, i, g, o, n, m, e, y
In roster form, the set is written as: {T, r, i, g, o, n, m, e, y}
In sets, repetition of elements is not allowed, so each letter is listed only once, regardless of how many times it appears in the word. Additionally, the order of elements in a set is irrelevant.
