-1-sinx=-1,5
-1+sin2x= -1,5

Answer 1

$1)- 1 - sin(x) = - frac{3}{2} \ - sin(x) = - frac{1}{2} \ sin(x) = frac{1}{2} \ x = frac{pi}{6} + 2pi : k, : kin : mathbb Z \ x = frac{5pi}{6} + pi : k, :k in mathbb Z$
$2) - 1 + sin(2x) = - frac{3}{2 } \ sin(2x) = - frac{1}{2} \ 2x = - frac{pi}{6} + 2pi : k, : kin : mathbb Z \ x = - frac{pi}{12} + pi : k ,: k in : mathbb Z : \ 2x = - frac{5pi}{6} + 2pi : k ,: k in : mathbb Z \ x = - frac{5pi}{12} + pi : k ,: k in : mathbb Z$
