arctan((-5sqrt(3))/5)

arctan (\frac{- 5 3}{5})

- \frac{π}{3}

Decimal Notation

- 60

Solution steps

arctan (\frac{- 5 3}{5})

Simplify

= arctan (- 3)

Use the following property:

arctan (- x) = - arctan (x)

arctan (- 3) = - arctan (3)

= - arctan (3)

Use the following trivial identity:

arctan (3) = \frac{π}{3}

arctan (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}{3}

= - \frac{π}{3}

\frac{12 \cdot sin ( 6 3 ^{\circ} )}{sin ( 8 0 ^{\circ} )}

sec (\frac{3}{2} π)

sinh (\frac{π}{4})

60 \cdot sin (3 7^{\circ})

\frac{14.7}{tan ( 23. 5 ^{\circ} )}
