Solution

1 + 2 cos (\frac{π}{6})

Solution

1 + 3

+1

Solution steps

1 + 2 cos (\frac{π}{6})

Use the following trivial identity:

cos (\frac{π}{6}) = \frac{3}{2}

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

Simplify

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

= 1 + 3

Popular Examples

(cos((11pi)/6))/(sin((11pi)/6))

\frac{cos ( \frac{11 π}{6} )}{sin ( \frac{11 π}{6} )}

3+2sin((3pi)/2)

3 + 2 sin (\frac{3 π}{2})

12.4-10(0.5pi-arcsin(0.5)-0.5(1-(0.5)^2)^{1/2})

12.4 - 10 (0.5 π - arcsin (0.5) - 0.5 (1 - (0.5)^{2})^{\frac{1}{2}})

sin (\frac{11}{9}) π

(1.24)/(tan(34))

\frac{1.24}{tan ( 3 4 ^{\circ} )}
