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

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

- \frac{π}{6}

Decimal Notation

- 30

Solution steps

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

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

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

\frac{1}{3} = \frac{3}{3}

\frac{1}{3}

Multiply by the conjugate

\frac{3}{3}

= \frac{1 \cdot 3}{3 3}

1 \cdot 3 = 3

33 = 3

33

Apply radical rule:

a a = a

33 = 3

= 3

= \frac{3}{3}

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

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

Use the following property:

arctan (- x) = - arctan (x)

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

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

Use the following trivial identity:

arctan (\frac{3}{3}) = \frac{π}{6}

arctan (\frac{3}{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}

cos (\frac{π}{5})

tan (- \frac{4 π}{3})

2 sin^{2} (x) + 3 cos (x) - 3 = 0

sin (\frac{17 π}{12})

sin (x) = - 1
