¿Qué es la implicación lógica y equivalencia lógica?
IMPLICACIÓN LÓGICA Y EQUIVALENCIA LÓGICA p ® q que sea tautología. En la columna resultado se observa los valores de verdad, en este caso todos son verdaderos. Entonces, afirmamos que la condicional es tautología, por tanto, es una implicación lógica.
¿Qué es la equivalencia lógica?
Si dos argumentos son lógicamente equivalentes, entonces también poseen los mismos valores de verdad. Esto es lo que llamamos equivalencia lógica y puede confundirse con la bicondicional, pero fácilmente lo podemos explicar con un sencillo ejemplo como sigue:
¿Cuál es la verdad para la equivalencia lógica?
En resumen, la verdad para la equivalencia lógica depende únicamente de los argumentos de p p y q q .
¿Cuál es la implicación lógica de la condicional?
Entonces, afirmamos que la condicional es tautología, por tanto, es una implicación lógica. Si en la columna resultado se obtiene contradicción o contingencia, entonces, no existe implicación lógica.
