arccos(-1)+arctan(sqrt(3))

arccos (- 1) + arctan (3)

π + \frac{π}{3}

Decimal Notation

240

Solution steps

arccos (- 1) + arctan (3)

Use the following trivial identity:

arccos (- 1) = π

arccos (- 1)

x - 1 - \frac{3}{2} - \frac{2}{2} - \frac{1}{2} 0 \frac{1}{2} \frac{2}{2} \frac{3}{2} 1 arccos (x) π \frac{5 π}{6} \frac{3 π}{4} \frac{2 π}{3} \frac{π}{2} \frac{π}{3} \frac{π}{4} \frac{π}{6} 0 arccos (x) 18 0^{\circ} 15 0^{\circ} 13 5^{\circ} 12 0^{\circ} 9 0^{\circ} 6 0^{\circ} 4 5^{\circ} 3 0^{\circ} 0^{\circ}

= π

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}

= π + \frac{π}{3}

sin (3 0^{\circ}) 4

sin (3 0^{\circ}) 5

arccos (\frac{17}{26})

arctan (\frac{9.4}{3.6})

\frac{589.3}{sin ( 20.8 5 ^{\circ} )}
