arctan((-1)/(-sqrt(3)))

解答

arctan (\frac{- 1}{- 3})

\frac{π}{6}

十进制

30

求解步骤

arctan (\frac{- 1}{- 3})

使用以下普通恒等式:

arctan (\frac{- 1}{- 3}) = \frac{π}{6}

arctan (\frac{- 1}{- 3})

x 0 \frac{3}{3} 13 arctan (x) 0 \frac{π}{6} \frac{π}{4} \frac{π}{3} arctan (x) 0^{\circ} 3 0^{\circ} 4 5^{\circ} 6 0^{\circ}

= \frac{π}{6}

= \frac{π}{6}

arccos (\frac{1}{8})

6 sin (4 5^{\circ})

arccos (cos (- \frac{7 π}{6}))

sin^{2} (4 0^{\circ}) + cos^{2} (4 0^{\circ})

csc (arctan (- \frac{8}{9}))
