sin((-13pi)/(12))

sin (\frac{- 13 π}{12})

- \frac{2 ( 1 - 3 )}{4}

Solution steps

sin (\frac{- 13 π}{12})

Simplify

= sin (- \frac{13 π}{12})

Use the following property:

sin (- x) = - sin (x)

sin (- \frac{13 π}{12}) = - sin (\frac{13 π}{12})

= - sin (\frac{13 π}{12})

Rewrite using trig identities:

sin (\frac{13 π}{12}) = \frac{2 ( 1 - 3 )}{4}

= - \frac{2 ( 1 - 3 )}{4}

sin (\frac{3 π}{7})

20 \cdot sin (4 5^{\circ})

8 \cdot cos (3 0^{\circ})

cot (- 4)

arctan (\frac{2}{11})
