12.1cos(30)

Solution

12.1 cos (3 0^{\circ})

Solution

\frac{121 3}{20}

+1

Solution steps

12.1 cos (3 0^{\circ})

= \frac{121}{10} cos (3 0^{\circ})

Use the following trivial identity:

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

= \frac{121}{10} \cdot \frac{3}{2}

Simplify

\frac{121}{10} \cdot \frac{3}{2} : \frac{121 3}{20}

= \frac{121 3}{20}
