Solution

1 + 2 cos (6 0^{\circ})

Solution

2

Solution steps

1 + 2 cos (6 0^{\circ})

Use the following trivial identity:

cos (6 0^{\circ}) = \frac{1}{2}

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

Simplify

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

= 2

cos(pi/2)-sin((5pi)/3)+tan((9pi)/4)-cos((5pi)/6)+tan((7pi)/6)

cos (\frac{π}{2}) - sin (\frac{5 π}{3}) + tan (\frac{9 π}{4}) - cos (\frac{5 π}{6}) + tan (\frac{7 π}{6})

1/2 sin(2*pi/4)

\frac{1}{2} sin (2 \cdot \frac{π}{4})
