-3pi+sin^2(-(3pi)/3)-8

- 3 π + sin^{2} (- \frac{3 π}{3}) - 8

- 3 π - 8

Solution steps

- 3 π + sin^{2} (- \frac{3 π}{3}) - 8

Simplify

= - 3 π + sin^{2} (- π) - 8

Use the following property:

sin (- x) = - sin (x)

sin (- π) = - sin (π)

= - 3 π + (- sin (π))^{2} - 8

Simplify

= - 3 π + sin^{2} (π) - 8

Use the following trivial identity:

sin (π) = 0

= - 3 π + 0^{2} - 8

Simplify

= - 3 π - 8

arcsin (0.15)
