9.81*cos(30)

Solution

9.81 \cdot cos (3 0^{\circ})

Solution

\frac{981 3}{200}

+1

Solution steps

9.81 cos (3 0^{\circ})

= \frac{981}{100} cos (3 0^{\circ})

Use the following trivial identity:

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

= \frac{981}{100} \cdot \frac{3}{2}

Simplify

\frac{981}{100} \cdot \frac{3}{2} : \frac{981 3}{200}

= \frac{981 3}{200}
