Question
Given that f(1) = 2, f'(1) = -1, g(1) = 0, and g'(1) = 1. If F(x) = f(x) cos cos (g (x)), then the value of F'(1) is?"
Solution
Para encontrar el valor de , primero necesitamos aplicar la regla del producto y la regla de la cadena a la función .
Primero, recordemos que la derivada de un producto de dos funciones y es:
En este caso, y .
Entonces, la derivada de es:
Ahora, necesitamos encontrar la derivada de usando la regla de la cadena. Sea , entonces:
Y la derivada de es:
Por lo tanto:
Ahora, sustituyamos esto en la derivada de :
Finalmente, evaluamos en :
Dado que , , , y , sustituimos estos valores:
Sabemos que y , entonces:
Por lo tanto, el valor de es .
