sin(arccos(-2/3)+2arcsin(-1/3))

sin (arccos (- \frac{2}{3}) + 2 arcsin (- \frac{1}{3}))

sin (arccos (- \frac{2}{3}) - 2 arcsin (\frac{1}{3}))

Decimal Notation

0.99874 \dots

Solution steps

sin (arccos (- \frac{2}{3}) + 2 arcsin (- \frac{1}{3}))

Use the following property:

arcsin (- x) = - arcsin (x)

arcsin (- \frac{1}{3}) = - arcsin (\frac{1}{3})

= sin (arccos (- \frac{2}{3}) + 2 (- arcsin (\frac{1}{3})))

= sin (arccos (- \frac{2}{3}) - 2 arcsin (\frac{1}{3}))

sin (2)

arccos (\frac{11241}{10800})

20.3 sin (3 7^{\circ})

6 (tan (1 0^{\circ}))

tan (2 0^{\circ}) + tan (2 5^{\circ})
