1/2 sin(1/2 pi/2)

Solution

\frac{1}{2} sin (\frac{1}{2} \frac{π}{2})

Solution

\frac{2}{4}

+1

Solution steps

\frac{1}{2} sin (\frac{1}{2} \cdot \frac{π}{2})

Simplify:

\frac{1}{2} \cdot \frac{π}{2} = \frac{π}{4}

\frac{1}{2} sin (\frac{π}{4}) = \frac{sin ( \frac{π}{4} )}{2}

= \frac{sin ( \frac{π}{4} )}{2}

Use the following trivial identity:

sin (\frac{π}{4}) = \frac{2}{2}

= \frac{\frac{2}{2}}{2}

Simplify

\frac{\frac{2}{2}}{2} : \frac{2}{4}

= \frac{2}{4}
