▼ IMPORTANT ▼ In this video we will see a solved exercise (solved example) of how to prove an inequality from the inequality of the triangle, using the definition of absolute value, dividing the problem into 2 cases, using the trick of adding and subtracting the same complex to separate the sum of 2 modules, everything explained step by step.

Impresionante demostración. Una pregunta ¿por qué cuando se aplica la definición de valor absoluto a |z1|-|z2|

Efectivamente, se trata de una resta de numeros reales menor que cero, es decir que es negativa
