expand (sin(x))/(2(1+cos(x)))

expand

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

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

Solution steps

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

Expand

2 (1 + cos (x)) : 2 + 2 cos (x)

= \frac{sin ( x )}{2 + 2 cos ( x )}

(- 1 + 3 i)^{8}

3 e^{3 x} \cdot (e^{3 x} + 1)

x (0, 1, 2, 3) y (- 1, - 1, - 1, - 1)

2 \cdot (ab (x + a))

- 2 (2 x - 1 = 17 - 4 x)
