simplify sin(arccos((-x)/3))

simplify

sin (arccos (\frac{- x}{3}))

\frac{9 - x ^{2}}{3}

Solution steps

sin (arccos (\frac{- x}{3}))

Use the following identity:

sin (arccos (x)) = 1 - x^{2}

= 1 - (\frac{- x}{3})^{2}

Simplify

= \frac{9 - x ^{2}}{3}

sin (2 cos^{(- 1)} (x))

tan (4 5^{\circ} - x)

1 + cos^{2} (x - 18 0^{\circ})

sin (2 x + \frac{π}{3})

cot (arccsc (x))
