4sin^2(pi/6)-1

Solution

4 sin^{2} (\frac{π}{6}) - 1

Solution

0

Solution steps

4 sin^{2} (\frac{π}{6}) - 1

Use the following trivial identity:

sin (\frac{π}{6}) = \frac{1}{2}

= 4 (\frac{1}{2})^{2} - 1

Simplify

4 (\frac{1}{2})^{2} - 1 : 0

= 0

Popular Examples

2(cos(pi/6)+isin(pi/6))*5(cos(pi/3)+isin(pi/3))

2 (cos (\frac{π}{6}) + i sin (\frac{π}{6})) \cdot 5 (cos (\frac{π}{3}) + i sin (\frac{π}{3}))

185 sin (1 5^{\circ})

\frac{1}{sin ( 12 0 ^{\circ} )}

cos((4pi)/3)+i*sin((4pi)/3)

cos (\frac{4 π}{3}) + i \cdot sin (\frac{4 π}{3})

arccos(2/(sqrt(3)\sqrt{2)})

arccos (\frac{2}{3 2})
