Find the Exact Value sec((5pi)/6)

sec (\frac{( 5 π )}{6})

- \frac{2 3}{3}

Decimal Notation

- 1.15470 \dots

Solution steps

sec (\frac{( 5 π )}{6})

= sec (\frac{5 π}{6})

Use the following trivial identity:

sec (\frac{5 π}{6}) = - \frac{2 3}{3}

sec (\frac{5 π}{6})

sec (x)

periodicity table with

2 πn

cycle:

x 0 \frac{π}{6} \frac{π}{4} \frac{π}{3} \frac{π}{2} \frac{2 π}{3} \frac{3 π}{4} \frac{5 π}{6} sec (x) 1 \frac{2 3}{3} 22 Undefined - 2 - 2 - \frac{2 3}{3} x π \frac{7 π}{6} \frac{5 π}{4} \frac{4 π}{3} \frac{3 π}{2} \frac{5 π}{3} \frac{7 π}{4} \frac{11 π}{6} sec (x) - 1 - \frac{2 3}{3} - 2 - 2 Undefined 22 \frac{2 3}{3}

= - \frac{2 3}{3}

= - \frac{2 3}{3}

a, tan (a) = \frac{1}{3}

tan (θ) = \frac{- 4}{5}

sec (\frac{( 5 π )}{3})

sin (x) = \frac{18.5}{20}

sec (\frac{( 2 π )}{3})
