arctan (tan (\frac{π}{4}))

Use the inverse trig property:

\frac{π}{4}

arctan (tan (\frac{π}{4}))

Für

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

- \frac{π}{2} < \frac{π}{4} < \frac{π}{2}

= \frac{π}{4}

= \frac{π}{4}

cos (\frac{19 π}{6})

- cos (4 5^{\circ})

sin (\frac{3 π}{5})

sin (- 31 5^{\circ})

cot (- 4 5^{\circ})
