tan(30)tan(60)

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

1

Solution steps

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

Use the following trivial identity:

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

Use the following trivial identity:

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

= \frac{3}{3} 3

Simplify

\frac{3}{3} 3 : 1

= 1

sin (\frac{π}{4} + \frac{π}{4})

arccos (\frac{30}{40})

36 \cdot sin (6 0^{\circ})

tan^{2} (\frac{5}{3}) π + 4 sin (\frac{5}{6}) π - 3 cot^{2} (\frac{5}{4}) π

2 + 3 cos (π)
