sin(-1((11sin(120))/(18)))

sin (- 1 (\frac{11 sin ( 12 0 ^{\circ} )}{18}))

- sin (\frac{11 sin ( \frac{2 π}{3} )}{18})

Decimal Notation

- 0.50487 \dots

Solution steps

sin (- 1 \cdot (\frac{11 sin ( 12 0 ^{\circ} )}{18}))

= sin (- 1 \cdot \frac{11 sin ( 12 0 ^{\circ} )}{18})

Use the following property:

sin (- x) = - sin (x)

sin (- 1 \frac{11 sin ( 12 0 ^{\circ} )}{18}) = - sin (1 \frac{11 sin ( 12 0 ^{\circ} )}{18})

= - sin (1 \cdot \frac{11 sin ( 12 0 ^{\circ} )}{18})

= - sin (\frac{11 sin ( 12 0 ^{\circ} )}{18})

3 cos (π)

cos (\frac{5}{13} + (- \frac{3}{5}))

tan (\frac{- 9 π}{4})

arctan (cot (13 5^{\circ}))

\frac{15}{sin ( 3 3 ^{\circ} )}
