csc((15pi)/8)

csc (\frac{15 π}{8})

- 2 2 - 2 - 2 2 - 2

Solution steps

csc (\frac{15 π}{8})

Rewrite using trig identities:

\frac{1}{sin ( \frac{15 π}{8} )}

= \frac{1}{sin ( \frac{15 π}{8} )}

Rewrite using trig identities:

sin (\frac{15 π}{8}) = - \frac{2 - 2}{2}

= \frac{1}{- \frac{2 - 2}{2}}

Simplify

\frac{1}{- \frac{2 - 2}{2}} : - 2 2 - 2 - 2 2 - 2

= - 2 2 - 2 - 2 2 - 2

2 tan (2 π)

- 10 sin (3 0^{\circ})

2 sin (\frac{7 π}{8})

arcsin (- 0.25)

\frac{7}{sin ( 6 5 ^{\circ} )}
