Integral(x^3*sin(4*x^2 - 6), (x, 0, 1))

Solución detallada

Usamos la integración por partes:

$\int \operatorname{u} \operatorname{dv} = \operatorname{u}\operatorname{v} - \int \operatorname{v} \operatorname{du}$

que $u{\left(x \right)} = x^{3}$ y que $\operatorname{dv}{\left(x \right)} = \sin{\left(4 x^{2} - 6 \right)}$ .

Entonces $\operatorname{du}{\left(x \right)} = 3 x^{2}$ .

Para buscar $v{\left(x \right)}$ :
Ahora resolvemos podintegral.
La integral del producto de una función por una constante es la constante por la integral de esta función:

$\int \frac{3 \sqrt{2} \sqrt{\pi} x^{2} \left(- \sin{\left(6 \right)} C\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right) + \cos{\left(6 \right)} S\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right)\right)}{4}\, dx = \frac{3 \sqrt{2} \sqrt{\pi} \int x^{2} \left(- \sin{\left(6 \right)} C\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right) + \cos{\left(6 \right)} S\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right)\right)\, dx}{4}$
1. Vuelva a escribir el integrando:
  
  $x^{2} \left(- \sin{\left(6 \right)} C\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right) + \cos{\left(6 \right)} S\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right)\right) = - x^{2} \sin{\left(6 \right)} C\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right) + x^{2} \cos{\left(6 \right)} S\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right)$
2. Integramos término a término:
  1. La integral del producto de una función por una constante es la constante por la integral de esta función:
    
    $\int \left(- x^{2} \sin{\left(6 \right)} C\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right)\right)\, dx = - \sin{\left(6 \right)} \int x^{2} C\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right)\, dx$
    1. No puedo encontrar los pasos en la búsqueda de esta integral.
      
      Pero la integral
      
      $\frac{x^{3} C\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right) \Gamma\left(\frac{1}{4}\right)}{12 \Gamma\left(\frac{5}{4}\right)} - \frac{\sqrt{2} x^{2} \sin{\left(4 x^{2} \right)} \Gamma\left(\frac{1}{4}\right)}{48 \sqrt{\pi} \Gamma\left(\frac{5}{4}\right)} - \frac{\sqrt{2} \cos{\left(4 x^{2} \right)} \Gamma\left(\frac{1}{4}\right)}{192 \sqrt{\pi} \Gamma\left(\frac{5}{4}\right)}$
    Por lo tanto, el resultado es: $- \left(\frac{x^{3} C\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right) \Gamma\left(\frac{1}{4}\right)}{12 \Gamma\left(\frac{5}{4}\right)} - \frac{\sqrt{2} x^{2} \sin{\left(4 x^{2} \right)} \Gamma\left(\frac{1}{4}\right)}{48 \sqrt{\pi} \Gamma\left(\frac{5}{4}\right)} - \frac{\sqrt{2} \cos{\left(4 x^{2} \right)} \Gamma\left(\frac{1}{4}\right)}{192 \sqrt{\pi} \Gamma\left(\frac{5}{4}\right)}\right) \sin{\left(6 \right)}$
  1. La integral del producto de una función por una constante es la constante por la integral de esta función:
    
    $\int x^{2} \cos{\left(6 \right)} S\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right)\, dx = \cos{\left(6 \right)} \int x^{2} S\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right)\, dx$
    1. No puedo encontrar los pasos en la búsqueda de esta integral.
      
      Pero la integral
      
      $\frac{x^{3} S\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right) \Gamma\left(\frac{3}{4}\right)}{4 \Gamma\left(\frac{7}{4}\right)} + \frac{\sqrt{2} x^{2} \cos{\left(4 x^{2} \right)} \Gamma\left(\frac{3}{4}\right)}{16 \sqrt{\pi} \Gamma\left(\frac{7}{4}\right)} - \frac{\sqrt{2} \sin{\left(4 x^{2} \right)} \Gamma\left(\frac{3}{4}\right)}{64 \sqrt{\pi} \Gamma\left(\frac{7}{4}\right)}$
    Por lo tanto, el resultado es: $\left(\frac{x^{3} S\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right) \Gamma\left(\frac{3}{4}\right)}{4 \Gamma\left(\frac{7}{4}\right)} + \frac{\sqrt{2} x^{2} \cos{\left(4 x^{2} \right)} \Gamma\left(\frac{3}{4}\right)}{16 \sqrt{\pi} \Gamma\left(\frac{7}{4}\right)} - \frac{\sqrt{2} \sin{\left(4 x^{2} \right)} \Gamma\left(\frac{3}{4}\right)}{64 \sqrt{\pi} \Gamma\left(\frac{7}{4}\right)}\right) \cos{\left(6 \right)}$
  El resultado es: $- \left(\frac{x^{3} C\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right) \Gamma\left(\frac{1}{4}\right)}{12 \Gamma\left(\frac{5}{4}\right)} - \frac{\sqrt{2} x^{2} \sin{\left(4 x^{2} \right)} \Gamma\left(\frac{1}{4}\right)}{48 \sqrt{\pi} \Gamma\left(\frac{5}{4}\right)} - \frac{\sqrt{2} \cos{\left(4 x^{2} \right)} \Gamma\left(\frac{1}{4}\right)}{192 \sqrt{\pi} \Gamma\left(\frac{5}{4}\right)}\right) \sin{\left(6 \right)} + \left(\frac{x^{3} S\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right) \Gamma\left(\frac{3}{4}\right)}{4 \Gamma\left(\frac{7}{4}\right)} + \frac{\sqrt{2} x^{2} \cos{\left(4 x^{2} \right)} \Gamma\left(\frac{3}{4}\right)}{16 \sqrt{\pi} \Gamma\left(\frac{7}{4}\right)} - \frac{\sqrt{2} \sin{\left(4 x^{2} \right)} \Gamma\left(\frac{3}{4}\right)}{64 \sqrt{\pi} \Gamma\left(\frac{7}{4}\right)}\right) \cos{\left(6 \right)}$
Por lo tanto, el resultado es: $\frac{3 \sqrt{2} \sqrt{\pi} \left(- \left(\frac{x^{3} C\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right) \Gamma\left(\frac{1}{4}\right)}{12 \Gamma\left(\frac{5}{4}\right)} - \frac{\sqrt{2} x^{2} \sin{\left(4 x^{2} \right)} \Gamma\left(\frac{1}{4}\right)}{48 \sqrt{\pi} \Gamma\left(\frac{5}{4}\right)} - \frac{\sqrt{2} \cos{\left(4 x^{2} \right)} \Gamma\left(\frac{1}{4}\right)}{192 \sqrt{\pi} \Gamma\left(\frac{5}{4}\right)}\right) \sin{\left(6 \right)} + \left(\frac{x^{3} S\left(\frac{2 \sqrt{2} x}{\sqrt{\pi}}\right) \Gamma\left(\frac{3}{4}\right)}{4 \Gamma\left(\frac{7}{4}\right)} + \frac{\sqrt{2} x^{2} \cos{\left(4 x^{2} \right)} \Gamma\left(\frac{3}{4}\right)}{16 \sqrt{\pi} \Gamma\left(\frac{7}{4}\right)} - \frac{\sqrt{2} \sin{\left(4 x^{2} \right)} \Gamma\left(\frac{3}{4}\right)}{64 \sqrt{\pi} \Gamma\left(\frac{7}{4}\right)}\right) \cos{\left(6 \right)}\right)}{4}$
Ahora simplificar:

$- \frac{\sqrt{2} \left(4 x^{2} \sin{\left(6 \right)} \sin{\left(4 x^{2} \right)} + 4 x^{2} \cos{\left(6 \right)} \cos{\left(4 x^{2} \right)} - \sin{\left(4 x^{2} \right)} \cos{\left(6 \right)} + \sin{\left(6 \right)} \cos{\left(4 x^{2} \right)}\right) \Gamma\left(\frac{1}{4}\right) \Gamma\left(\frac{3}{4}\right)}{64 \pi}$
Añadimos la constante de integración:

$- \frac{\sqrt{2} \left(4 x^{2} \sin{\left(6 \right)} \sin{\left(4 x^{2} \right)} + 4 x^{2} \cos{\left(6 \right)} \cos{\left(4 x^{2} \right)} - \sin{\left(4 x^{2} \right)} \cos{\left(6 \right)} + \sin{\left(6 \right)} \cos{\left(4 x^{2} \right)}\right) \Gamma\left(\frac{1}{4}\right) \Gamma\left(\frac{3}{4}\right)}{64 \pi}+ \mathrm{constant}$

Respuesta:

$- \frac{\sqrt{2} \left(4 x^{2} \sin{\left(6 \right)} \sin{\left(4 x^{2} \right)} + 4 x^{2} \cos{\left(6 \right)} \cos{\left(4 x^{2} \right)} - \sin{\left(4 x^{2} \right)} \cos{\left(6 \right)} + \sin{\left(6 \right)} \cos{\left(4 x^{2} \right)}\right) \Gamma\left(\frac{1}{4}\right) \Gamma\left(\frac{3}{4}\right)}{64 \pi}+ \mathrm{constant}$
