2 πn

cycle:

x 0 \frac{π}{6} \frac{π}{4} \frac{π}{3} \frac{π}{2} \frac{2 π}{3} \frac{3 π}{4} \frac{5 π}{6} sin (x) 0 \frac{1}{2} \frac{2}{2} \frac{3}{2} 1 \frac{3}{2} \frac{2}{2} \frac{1}{2} x π \frac{7 π}{6} \frac{5 π}{4} \frac{4 π}{3} \frac{3 π}{2} \frac{5 π}{3} \frac{7 π}{4} \frac{11 π}{6} sin (x) 0 - \frac{1}{2} - \frac{2}{2} - \frac{3}{2} - 1 - \frac{3}{2} - \frac{2}{2} - \frac{1}{2}

= 0

= 0^{5}

Simplify

= 0

\frac{sin ( \frac{4 π}{3} )}{tan ( \frac{π}{4} ) + cos ( \frac{5 π}{6} )}

4 cos^{2} (15 0^{\circ}) + 3 tan (22 5^{\circ}) + 9 csc^{2} (30 0^{\circ})

2 cos (4 π)

cos (arcsin (\frac{7}{25}))

4 + 4 cos (\frac{π}{6})
