expand sin(-pi/4)sin(-pi/(12))

expand

sin (- \frac{π}{4}) sin (- \frac{π}{12})

\frac{3}{4} - \frac{1}{4}

Decimal Notation

0.18301 \dots

Solution steps

sin (- \frac{π}{4}) sin (- \frac{π}{12})

sin (- \frac{π}{4}) = - \frac{2}{2}

= - \frac{2}{2} sin (- \frac{π}{12})

sin (- \frac{π}{12}) = - \frac{6 - 2}{4}

= - \frac{2}{2} (- \frac{6 - 2}{4})

Simplify

= \frac{3}{4} - \frac{1}{4}

\frac{3 + x}{x ( x + 1 )}

\frac{5 x ^{2} - 25 x + 20}{- 3 x ^{2} + 24 x - 48}

\frac{( 0.13 + y ) ( y )}{0.13 - y}

\frac{( n + 1 ) ^{p n}}{( e ^{n + 1} ) n ^{p}}

(5 + 3) 2
