expand 2sin(pi/3)*cos(pi/3)-1

expand

2 sin (\frac{π}{3}) \cdot cos (\frac{π}{3}) - 1

\frac{3}{2} - 1

Decimal Notation

- 0.13397 \dots

Solution steps

2 sin (\frac{π}{3}) cos (\frac{π}{3}) - 1

2 sin (\frac{π}{3}) cos (\frac{π}{3}) = \frac{3}{2}

= \frac{3}{2} - 1

\frac{x ^{2}}{( z - 1 ) ( z + 0.5 )}

\frac{( 1 + cos ( x ) ) ^{2} + sin ^{(2)} ( x )}{1 + cos ( x )}

r (1.16 - 0.58 r + 0.298 r^{2} = 0)

\frac{- k c ^{k - 1} + 2 c ^{k - 1}}{( k + 2 ) ( k + 1 )}

\frac{( ( s + π ) e ^{- s} )}{s ^{2} + π ^{2}}
