Pasos de solución

\int 8 sin^{2} (x - \frac{π}{12}) d x

Sacar la constante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 8 \cdot \int sin^{2} (x - \frac{π}{12}) d x

Aplicar integración por sustitución

: \int sin^{2} (u) d u

= 8 \cdot \int sin^{2} (u) d u

Re-escribir usando identidades trigonométricas

= 8 \cdot \int \frac{1 - cos ( 2 u )}{2} d u

Sacar la constante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 8 \cdot \frac{1}{2} \cdot \int 1 - cos (2 u) d u

Aplicar la regla de la suma:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= 8 \cdot \frac{1}{2} (\int 1 d u - \int cos (2 u) d u)

\int 1 d u = u

\int cos (2 u) d u = \frac{1}{2} sin (2 u)

= 8 \cdot \frac{1}{2} (u - \frac{1}{2} sin (2 u))

Sustituir en la ecuación

u = x - \frac{π}{12}

= 8 \cdot \frac{1}{2} (x - \frac{π}{12} - \frac{1}{2} sin (2 (x - \frac{π}{12})))

Simplificar
