Integral(-1/((2*sin(y))*cos(y)^3), (y, 0, 1))

Solución detallada

La integral del producto de una función por una constante es la constante por la integral de esta función:

$\int \left(- \frac{1}{2 \sin{\left(y \right)} \cos^{3}{\left(y \right)}}\right)\, dy = - \int \frac{1}{2 \sin{\left(y \right)} \cos^{3}{\left(y \right)}}\, dy$
1. No puedo encontrar los pasos en la búsqueda de esta integral.
  
  Pero la integral
  
  $- \frac{\log{\left(\tan{\left(\frac{y}{2} \right)} - 1 \right)} \tan^{4}{\left(\frac{y}{2} \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2} + \frac{2 \log{\left(\tan{\left(\frac{y}{2} \right)} - 1 \right)} \tan^{2}{\left(\frac{y}{2} \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2} - \frac{\log{\left(\tan{\left(\frac{y}{2} \right)} - 1 \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2} - \frac{\log{\left(\tan{\left(\frac{y}{2} \right)} + 1 \right)} \tan^{4}{\left(\frac{y}{2} \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2} + \frac{2 \log{\left(\tan{\left(\frac{y}{2} \right)} + 1 \right)} \tan^{2}{\left(\frac{y}{2} \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2} - \frac{\log{\left(\tan{\left(\frac{y}{2} \right)} + 1 \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2} + \frac{\log{\left(\tan{\left(\frac{y}{2} \right)} \right)} \tan^{4}{\left(\frac{y}{2} \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2} - \frac{2 \log{\left(\tan{\left(\frac{y}{2} \right)} \right)} \tan^{2}{\left(\frac{y}{2} \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2} + \frac{\log{\left(\tan{\left(\frac{y}{2} \right)} \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2} + \frac{2 \tan^{2}{\left(\frac{y}{2} \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2}$
Por lo tanto, el resultado es: $\frac{\log{\left(\tan{\left(\frac{y}{2} \right)} - 1 \right)} \tan^{4}{\left(\frac{y}{2} \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2} - \frac{2 \log{\left(\tan{\left(\frac{y}{2} \right)} - 1 \right)} \tan^{2}{\left(\frac{y}{2} \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2} + \frac{\log{\left(\tan{\left(\frac{y}{2} \right)} - 1 \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2} + \frac{\log{\left(\tan{\left(\frac{y}{2} \right)} + 1 \right)} \tan^{4}{\left(\frac{y}{2} \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2} - \frac{2 \log{\left(\tan{\left(\frac{y}{2} \right)} + 1 \right)} \tan^{2}{\left(\frac{y}{2} \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2} + \frac{\log{\left(\tan{\left(\frac{y}{2} \right)} + 1 \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2} - \frac{\log{\left(\tan{\left(\frac{y}{2} \right)} \right)} \tan^{4}{\left(\frac{y}{2} \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2} + \frac{2 \log{\left(\tan{\left(\frac{y}{2} \right)} \right)} \tan^{2}{\left(\frac{y}{2} \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2} - \frac{\log{\left(\tan{\left(\frac{y}{2} \right)} \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2} - \frac{2 \tan^{2}{\left(\frac{y}{2} \right)}}{2 \tan^{4}{\left(\frac{y}{2} \right)} - 4 \tan^{2}{\left(\frac{y}{2} \right)} + 2}$
Ahora simplificar:

$\frac{\left(\tan{\left(\frac{y}{2} \right)} - 1\right)^{2} \left(\tan{\left(\frac{y}{2} \right)} + 1\right)^{2} \left(\left(\cos{\left(y \right)} - 1\right)^{2} \log{\left(\tan{\left(\frac{y}{2} \right)} - 1 \right)} + \left(\cos{\left(y \right)} - 1\right)^{2} \log{\left(\tan{\left(\frac{y}{2} \right)} + 1 \right)} - \left(\cos{\left(y \right)} - 1\right)^{2} \log{\left(\tan{\left(\frac{y}{2} \right)} \right)} + \left(\cos{\left(2 y \right)} - 1\right) \log{\left(\tan{\left(\frac{y}{2} \right)} - 1 \right)} + \left(\cos{\left(2 y \right)} - 1\right) \log{\left(\tan{\left(\frac{y}{2} \right)} + 1 \right)} - \left(\cos{\left(2 y \right)} - 1\right) \log{\left(\tan{\left(\frac{y}{2} \right)} \right)} + \cos{\left(2 y \right)} - 1\right) + 4 \left(\log{\left(\tan{\left(\frac{y}{2} \right)} - 1 \right)} + \log{\left(\tan{\left(\frac{y}{2} \right)} + 1 \right)} - \log{\left(\tan{\left(\frac{y}{2} \right)} \right)}\right) \cos^{2}{\left(y \right)}}{8 \left(\tan{\left(\frac{y}{2} \right)} - 1\right)^{2} \left(\tan{\left(\frac{y}{2} \right)} + 1\right)^{2} \cos^{2}{\left(y \right)}}$
Añadimos la constante de integración:

$\frac{\left(\tan{\left(\frac{y}{2} \right)} - 1\right)^{2} \left(\tan{\left(\frac{y}{2} \right)} + 1\right)^{2} \left(\left(\cos{\left(y \right)} - 1\right)^{2} \log{\left(\tan{\left(\frac{y}{2} \right)} - 1 \right)} + \left(\cos{\left(y \right)} - 1\right)^{2} \log{\left(\tan{\left(\frac{y}{2} \right)} + 1 \right)} - \left(\cos{\left(y \right)} - 1\right)^{2} \log{\left(\tan{\left(\frac{y}{2} \right)} \right)} + \left(\cos{\left(2 y \right)} - 1\right) \log{\left(\tan{\left(\frac{y}{2} \right)} - 1 \right)} + \left(\cos{\left(2 y \right)} - 1\right) \log{\left(\tan{\left(\frac{y}{2} \right)} + 1 \right)} - \left(\cos{\left(2 y \right)} - 1\right) \log{\left(\tan{\left(\frac{y}{2} \right)} \right)} + \cos{\left(2 y \right)} - 1\right) + 4 \left(\log{\left(\tan{\left(\frac{y}{2} \right)} - 1 \right)} + \log{\left(\tan{\left(\frac{y}{2} \right)} + 1 \right)} - \log{\left(\tan{\left(\frac{y}{2} \right)} \right)}\right) \cos^{2}{\left(y \right)}}{8 \left(\tan{\left(\frac{y}{2} \right)} - 1\right)^{2} \left(\tan{\left(\frac{y}{2} \right)} + 1\right)^{2} \cos^{2}{\left(y \right)}}+ \mathrm{constant}$

Respuesta:

$\frac{\left(\tan{\left(\frac{y}{2} \right)} - 1\right)^{2} \left(\tan{\left(\frac{y}{2} \right)} + 1\right)^{2} \left(\left(\cos{\left(y \right)} - 1\right)^{2} \log{\left(\tan{\left(\frac{y}{2} \right)} - 1 \right)} + \left(\cos{\left(y \right)} - 1\right)^{2} \log{\left(\tan{\left(\frac{y}{2} \right)} + 1 \right)} - \left(\cos{\left(y \right)} - 1\right)^{2} \log{\left(\tan{\left(\frac{y}{2} \right)} \right)} + \left(\cos{\left(2 y \right)} - 1\right) \log{\left(\tan{\left(\frac{y}{2} \right)} - 1 \right)} + \left(\cos{\left(2 y \right)} - 1\right) \log{\left(\tan{\left(\frac{y}{2} \right)} + 1 \right)} - \left(\cos{\left(2 y \right)} - 1\right) \log{\left(\tan{\left(\frac{y}{2} \right)} \right)} + \cos{\left(2 y \right)} - 1\right) + 4 \left(\log{\left(\tan{\left(\frac{y}{2} \right)} - 1 \right)} + \log{\left(\tan{\left(\frac{y}{2} \right)} + 1 \right)} - \log{\left(\tan{\left(\frac{y}{2} \right)} \right)}\right) \cos^{2}{\left(y \right)}}{8 \left(\tan{\left(\frac{y}{2} \right)} - 1\right)^{2} \left(\tan{\left(\frac{y}{2} \right)} + 1\right)^{2} \cos^{2}{\left(y \right)}}+ \mathrm{constant}$
