Solution

\frac{1}{4}

+1

Decimal Notation

0.25

Solution steps

0.5 sin (3 0^{\circ})

= \frac{1}{2} sin (3 0^{\circ})

Use the following trivial identity:

sin (3 0^{\circ}) = \frac{1}{2}

sin (3 0^{\circ})

sin (x)

= \frac{1}{2}

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

Simplify

\frac{1}{2} \cdot \frac{1}{2} : \frac{1}{4}

\frac{1}{2} \cdot \frac{1}{2}

Multiply fractions:

\frac{a}{b} \cdot \frac{c}{d} = \frac{a \cdot c}{b \cdot d}

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

Multiply the numbers:

1 \cdot 1 = 1

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

Multiply the numbers:

2 \cdot 2 = 4

= \frac{1}{4}

= \frac{1}{4}
