sin(60)+cos(30)

sin (6 0^{\circ}) + cos (3 0^{\circ})

3

Solution steps

sin (6 0^{\circ}) + cos (3 0^{\circ})

Use the following trivial identity:

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

Use the following trivial identity:

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

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

Simplify

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

= 3

sin (π) + cos (π)

500 sin (3 0^{\circ})

sin (3 \cdot π)

arctan (- 1.4)

cot (7 0^{\circ})
