Halla $$$\int \left(- 2 x^{3} \sin{\left(1 \right)}\right)\, dx$$$.
Solución
Aplica la regla del factor constante $$$\int c f{\left(x \right)}\, dx = c \int f{\left(x \right)}\, dx$$$ con $$$c=- 2 \sin{\left(1 \right)}$$$ y $$$f{\left(x \right)} = x^{3}$$$:
$${\color{red}{\int{\left(- 2 x^{3} \sin{\left(1 \right)}\right)d x}}} = {\color{red}{\left(- 2 \sin{\left(1 \right)} \int{x^{3} d x}\right)}}$$
Aplica la regla de la potencia $$$\int x^{n}\, dx = \frac{x^{n + 1}}{n + 1}$$$ $$$\left(n \neq -1 \right)$$$ con $$$n=3$$$:
$$- 2 \sin{\left(1 \right)} {\color{red}{\int{x^{3} d x}}}=- 2 \sin{\left(1 \right)} {\color{red}{\frac{x^{1 + 3}}{1 + 3}}}=- 2 \sin{\left(1 \right)} {\color{red}{\left(\frac{x^{4}}{4}\right)}}$$
Por lo tanto,
$$\int{\left(- 2 x^{3} \sin{\left(1 \right)}\right)d x} = - \frac{x^{4} \sin{\left(1 \right)}}{2}$$
Añade la constante de integración:
$$\int{\left(- 2 x^{3} \sin{\left(1 \right)}\right)d x} = - \frac{x^{4} \sin{\left(1 \right)}}{2}+C$$
Respuesta
$$$\int \left(- 2 x^{3} \sin{\left(1 \right)}\right)\, dx = - \frac{x^{4} \sin{\left(1 \right)}}{2} + C$$$A
