expand 1/2 cos(2(x-pi))

expand

\frac{1}{2} cos (2 (x - π))

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

Solution steps

\frac{1}{2} cos (2 (x - π))

Expand

2 (x - π) : 2 x - 2 π

= \frac{1}{2} cos (2 x - 2 π)

Rewrite using trig identities

= \frac{1}{2} cos (2 x)

\frac{14}{( s + 2 ) ( s + 14 )}

((x - 1) \cdot 2^{x + 1}) \cdot 2.5

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

so l v e (3 x^{2} + 6 x = 0)

\frac{( m - n ) ^{2} + 6 ( m - n )}{9}
