Soal Latihan (Practice Questions)
1. Nyatakan dalam bentuk kalimat:
(Translate the following symbolic logic expressions into statements in words)
a.
Translation:
"There exists an such that is true and for all , if is true, then ."
Meaning: There is exactly one for which property is true.
b.
Translation:
"There exist and such that , and both and are true."
Meaning: There are at least two different values of and for which property holds.
2. Tulislah dalam bentuk simbol:
(Convert the following verbal statements into symbolic form)
a. Terdapat yang merupakan anggota dan bersifat .
Symbolic form:
(There exists a that is an element of and has property .)
b. Semua yang positif bersifat .
Symbolic form:
(For all , if is positive, then is true.)
c. Paling banyak ada satu yang memenuhi sifat .
Symbolic form:
(At most one satisfies property , meaning if two values satisfy , they must be equal.)
d. Sekurang-kurangnya ada satu bilangan real yang memenuhi sifat .
Symbolic form:
(There exists at least one real number that satisfies property .)
e. Paling banyak ada satu bilangan positif yang memenuhi sifat .
Symbolic form:
(At most one positive number satisfies property .)
f. Hanya terdapat satu yang memenuhi .
Symbolic form:
(There exists exactly one that satisfies property .)
g. Terdapat bilangan yang memenuhi di mana untuk setiap bilangan positif terdapat bilangan positif yang bersifat .
Symbolic form:
(There exists a number such that for every positive number , there exists a positive such that .)
Would you like further details on any specific part or additional examples? Here are some related questions to expand your understanding:
- How does the uniqueness quantifier differ from the existential quantifier ?
- What is the logical implication () used for in these symbolic forms?
- Can you provide a real-world example where the statement "There exists at least one real number satisfying property " might apply?
- How would you rewrite the expression in terms of set notation?
- What is the significance of in mathematical analysis?
Tip: When translating logic statements, always focus on the quantifiers () and connectives () to maintain the correct meaning of the original statement.
