arctan (tan (\frac{2 π}{5}))

Use the inverse trig property:

\frac{2 π}{5}

arctan (tan (\frac{2 π}{5}))

Für

- \frac{π}{2} < x < \frac{π}{2}, a rc t an (t an (x)) = x

- \frac{π}{2} < \frac{2 π}{5} < \frac{π}{2}

= \frac{2 π}{5}

= \frac{2 π}{5}

[2 (cos (1 5^{\circ}) + i sin (1 5^{\circ}))]^{3}

tan (\frac{π}{6} - \frac{5 π}{4})

6 cos (7 0^{\circ})

arctan (0.58)

arctan (0.83)
