cos(60)+sin(60)

cos (6 0^{\circ}) + sin (6 0^{\circ})

\frac{1 + 3}{2}

Solution steps

cos (6 0^{\circ}) + sin (6 0^{\circ})

Use the following trivial identity:

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

Use the following trivial identity:

sin (6 0^{\circ}) = \frac{3}{2}

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

Simplify

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

= \frac{1 + 3}{2}

tan^{2} (57. 5^{\circ})

1 - 2 sin^{2} (\frac{π}{6})

58 cos (3 0^{\circ})

\frac{5 sin ( - 0.01 )}{( - 0.01 )}

cot (\frac{π ( - 6.1 )}{6})
