Tasa de cambio instantánea

Imagina un coche que recorre una distancia de 50 km en un lapso de 40 min, y el conductor quiere saber la tasa de variación de la distancia en cualquier momento durante esos 40 min. O imagina que las existencias de una empresa fluctúan cada dos segundos y, para controlarlas adecuadamente, hay que calcular la tasa de variación de la cantidad de existencias por unidad de tiempo.

Saltar a un capítulo clave

    Estos son algunos de los escenarios en los que es necesario calcular la tasa de variación instantánea de una cantidad con respecto a otra cantidad. Las aplicaciones de este concepto son muy amplias en distintos campos, y a veces el número de cantidades no se limita a dos en algunas situaciones complicadas. Pero para el ámbito de este artículo, restringiremos nuestro estudio de la Tasa de Cambio Instantánea a dos cantidades solamente.

    Tasa de variación instantánea en un punto

    En el artículo adjunto sobre la Tasa de variación media, se ha tratado cómo calcular la tasa de variación de una cantidad a lo largo de un intervalo considerable de otra cantidad, pero ¿qué ocurre con la tasa de variación en un momento concreto? En un sentido amplio, queremos saber cómo cambia una cantidad en un momento concreto y no a lo largo de una gran parte del mismo.

    La Tasa de Cambio Instantánea en un punto de una curva es la tasa a la que cambia la cantidad respecto a la otra en ese punto (o instante).

    La Tasa de Cambio Instantánea en un punto es la pendiente de la curva en ese punto. Recuerda la definición de gradiente: el gradiente en un punto nos indica la tasa de cambio en ese punto.

    Tasa de cambio instantánea, Tangente como tasa de cambio, StudySmarterLa tangente en un punto significa su pendiente, StudySmarter Originals

    En el diagrama anterior, supongamos que queremos conocer la Tasa de Cambio Instantánea en el punto A, entonces necesitamos hallar el gradiente de la curva en el punto A. Y el gradiente en ese punto es la pendiente en ese punto.

    Para cualquier curva, variará de un punto a otro y la pendiente en ese punto debe calcularse individualmente.

    Un caso especial e intrigante es una línea recta, en la que la pendiente en cada punto sería la misma y, por tanto, la tasa de variación instantánea sería igual a la tasa media en cualquier intervalo.

    Tasa de variación instantánea mediante cálculo

    Aquí resulta muy útil una importante herramienta del cálculo, la diferenciación . Recuerda que diferenciar una función es hallar la pendiente de la curva en ese punto. Pero la pendiente en ese punto, como hemos visto, es latasa de variación instantánea en ese punto. Por tanto, podemos utilizar el cálculo para hallar la tasa de variación.

    Esto implica una propiedad muy crucial: la tasa de variación instantánea de y respecto a x es recíproca de la tasa de variación instantánea de x respecto a y.

    Tasa de variación instantánea como límites

    Ya hemos visto cómo podemos calcular la tasa de variación instantánea utilizando derivadas, pero ¿de dónde sale? ¿Cómo lo deducimos? Aquí exploraremos cómo ayudan los límites a relacionar la tasa de variación instantánea con las derivadas.

    Recuerda que la tasa de variación media se toma a lo largo de un intervalo grande y viene dada por

para evitar que ambos puntos se fusionen.

    Observa ahora que a medida que A y B se acercan más y más, la distancia entre ellos es infinitesimalmente pequeña y la recta que trazamos a través de ellos se convierte en una recta tangente:

    Tasa de variación instantánea, Dos puntos infinitesimalmente próximos, StudySmarterDos puntos infinitesimalmente próximos, StudySmarter Originals

    Como puede verse, a medida que la distancia entre los puntos se aproxima a 0, la recta secante se convierte en una recta tangente y la razón de cambio media se convierte en una razón de cambio instantánea en ese punto. Si hacemos zoom sobre los dos puntos, vemos que la curva se convierte en una recta y nuestra proposición de tangente queda geométricamente justificada:

     Tasa de variación instantánea, Dos puntos infinitamente próximos, StudySmarterDos puntos infinitamente próximos que resultan en una tangente, StudySmarter Originals

    Podemos nombrar las coordenadas en A como x, fx y dejar las coordenadas del punto B como (x+a, fx+a) ya que los valores variarán muy poco al estar muy próximos entre sí.

    Por tanto, la tasa de variación de y respecto a x es 32 en el punto (2,1).

    Tasa de variación instantánea - Puntos clave

    • La Tasa de Cambio Instantánea en un punto de una curva es la velocidad a la que cambia la cantidad respecto a la otra en ese punto (o instante).
    • La tasa de variación en un punto de una curva es la pendiente de la recta tangente trazada en ese punto.
