180+arctan((-1)/(-1))

180 + arctan (\frac{- 1}{- 1})

180 + \frac{π}{4}

Solution steps

180 + arctan (\frac{- 1}{- 1})

Use the following trivial identity:

arctan (\frac{- 1}{- 1}) = \frac{π}{4}

= 180 + \frac{π}{4}

tan (- 1) (\frac{- 0.756}{- 0.864})

16 π - 16 π cos (1.5 π)

cos (33 0^{\circ}) csc (15 0^{\circ}) - tan (15 0^{\circ}) sec (21 0^{\circ})

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

sin (2 \frac{3}{5})
