Schritte zur Lösung

arctan (tan (- \frac{3 π}{7}))

Use the inverse trig property:

- \frac{3 π}{7}

arctan (tan (- \frac{3 π}{7}))

Für

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

- \frac{π}{2} < - \frac{3 π}{7} < \frac{π}{2}

= - \frac{3 π}{7}

= - \frac{3 π}{7}

sin (10 0^{\circ}) cos (4 0^{\circ}) - cos (10 0^{\circ}) sin (4 0^{\circ})

cos (0^{2})

\frac{2}{sin ( 4 5 ^{\circ} )}

tan (0.25)

cos^{2} (7)
