Solution

Para encontrar la ecuación de la normal a la curva y=12x2 y = \frac{1}{2}x - 2 en el punto donde x=3 x = 3 , sigue estos pasos:

  1. Encuentra el valor de y y en x=3 x = 3 : y=12(3)2=322=3242=12 y = \frac{1}{2}(3) - 2 = \frac{3}{2} - 2 = \frac{3}{2} - \frac{4}{2} = -\frac{1}{2} Entonces, el punto en la curva es (3,12) (3, -\frac{1}{2}) .

  2. Calcula la pendiente de la curva en x=3 x = 3 : La ecuación de la curva es una línea recta, y su pendiente es el coeficiente de x x , que es 12 \frac{1}{2} .

  3. Encuentra la pendiente de la normal: La pendiente de la normal es el negativo del recíproco de la pendiente de la curva. Entonces, si la pendiente de la curva es 12 \frac{1}{2} , la pendiente de la normal es: mnormal=112=2 m_{\text{normal}} = -\frac{1}{\frac{1}{2}} = -2

  4. Usa la fórmula de la recta con pendiente y un punto: La fórmula de la recta es yy1=m(xx1) y - y_1 = m(x - x_1) , donde (x1,y1) (x_1, y_1) es el punto en la curva y m m es la pendiente de la normal. y(12)=2(x3) y - \left(-\frac{1}{2}\right) = -2(x - 3) Simplificando: y+12=2x+6 y + \frac{1}{2} = -2x + 6 y=2x+612 y = -2x + 6 - \frac{1}{2} y=2x+12212 y = -2x + \frac{12}{2} - \frac{1}{2} y=2x+112 y = -2x + \frac{11}{2}

Entonces, la ecuación de la normal a la curva en el punto donde x=3 x = 3 es: y=2x+112 y = -2x + \frac{11}{2}
