cos((2pi)/3)-arctan(1)

cos (\frac{2 π}{3}) - arctan (1)

- \frac{1}{2} - \frac{π}{4}

Solution steps

cos (\frac{2 π}{3}) - arctan (1)

Use the following trivial identity:

cos (\frac{2 π}{3}) = - \frac{1}{2}

Use the following trivial identity:

arctan (1) = \frac{π}{4}

= - \frac{1}{2} - \frac{π}{4}

cot (arccos (- \frac{2}{5}))

40 sin (7 0^{\circ})

58 sin (6 0^{\circ})

8 cos (5 1^{\circ})

e^{- c o s (0)}
