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

expand

2 + \frac{1}{2} cos (π (x + 1))

2 - \frac{1}{2} cos (π x)

Solution steps

2 + \frac{1}{2} cos (π (x + 1))

\frac{1}{2} cos (π (x + 1)) = - \frac{1}{2} cos (π x)

= 2 - \frac{1}{2} cos (π x)

cos (2 t) - cos (2 (t - 2 π)) U (t - 2 π)

\frac{1}{x \cdot ( x - 1 ) \cdot ( x - 2 ) \cdot ( x - 3 )}

\frac{10 s + 2}{( s + 5 ) ( s + 1 )}

sec^{2} (x) - 1

(x^{2} + y^{2} = 34) 2
