Six Sixes

Write each integer as a combination of 6 6's. Any mathematical symbol is allowed except for digits that are not 6.

$1 = \dfrac{6 + 6 + 6}{6 + 6 + 6}$

$2 = \dfrac{6}{6} + \dfrac{6 + 6}{6 + 6}$

$3 = \dfrac{6}{6} + \dfrac{6}{6} + \dfrac{6}{6}$

$4 = \dfrac{6 + 6}{6} + \dfrac{6 + 6}{6}$

$5 = 6 - \dfrac{6 + 6}{6 + 6} + \sin{\left(6 \pi\right)}$

$6 = 6 + \dfrac{6 + 6}{6 + 6} - \cos{\left(6 \pi\right)}$

$7 = 6 + \dfrac{6+6}{6+6} + \sin{\left(6 \pi\right)}$

$8 = \left( \sqrt{ \dfrac{6+6}{6} + 6 - 6 } \right)^6$

$9 = 6 \left( \dfrac{6 + 6 + 6}{6 + 6} \right)$
