Solution steps

- 2 arcsec (- 2)

Use the following trivial identity:

arcsec (- 2) = \frac{2 π}{3}

arcsec (- 2)

x 1 \frac{2 3}{3} 22 - 2 - 2 - \frac{2 3}{3} - 1 arcsec (x) 0 \frac{π}{6} \frac{π}{4} \frac{π}{3} \frac{2 π}{3} \frac{3 π}{4} \frac{5 π}{6} π arcsec (x) 0^{\circ} 3 0^{\circ} 4 5^{\circ} 6 0^{\circ} 12 0^{\circ} 13 5^{\circ} 15 0^{\circ} 18 0^{\circ}

= \frac{2 π}{3}

= - 2 \cdot \frac{2 π}{3}

Simplify

- 2 \cdot \frac{2 π}{3} : - \frac{4 π}{3}

- 2 \cdot \frac{2 π}{3}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= - \frac{2 π 2}{3}

Multiply the numbers:

2 \cdot 2 = 4

= - \frac{4 π}{3}

= - \frac{4 π}{3}
