(sin(30))(cot(30))(sec(30))

(sin (3 0^{\circ})) (cot (3 0^{\circ})) (sec (3 0^{\circ}))

1

Solution steps

(sin (3 0^{\circ})) (cot (3 0^{\circ})) (sec (3 0^{\circ}))

= sin (3 0^{\circ}) cot (3 0^{\circ}) sec (3 0^{\circ})

Use the following trivial identity:

sin (3 0^{\circ}) = \frac{1}{2}

Use the following trivial identity:

cot (3 0^{\circ}) = 3

Use the following trivial identity:

sec (3 0^{\circ}) = \frac{2 3}{3}

= \frac{1}{2} 3 \frac{2 3}{3}

Simplify

\frac{1}{2} 3 \frac{2 3}{3} : 1

= 1

arccos (\frac{4.4}{8})

\frac{9 sin ( - 0.1 )}{- 0.1}

\frac{0.8}{cos ( 4 1 ^{\circ} )}

cos (143.1 3^{\circ})

arctan (\frac{- \frac{3}{2}}{- \frac{1}{2}})
