5tan(180)-2sin(360)-tan(60)

5 tan (18 0^{\circ}) - 2 sin (36 0^{\circ}) - tan (6 0^{\circ})

- 3

Solution steps

5 tan (18 0^{\circ}) - 2 sin (36 0^{\circ}) - tan (6 0^{\circ})

Use the following trivial identity:

tan (18 0^{\circ}) = 0

Rewrite using trig identities:

sin (36 0^{\circ}) = 0

Use the following trivial identity:

tan (6 0^{\circ}) = 3

= 5 \cdot 0 - 2 \cdot 0 - 3

Simplify

= - 3

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

sin (\frac{3}{5} - \frac{5}{13})

sin (\frac{3 π}{5}) cos (\frac{3 π}{5})

sec (10 π)

arccos (cos (\frac{9 π}{5}))
