expand sin((pi(2n+1))/2)

expand

sin (\frac{π ( 2 n + 1 )}{2})

sin (\frac{2 πn + π}{2})

Solution steps

sin (\frac{π ( 2 n + 1 )}{2})

\frac{π ( 2 n + 1 )}{2} = \frac{2 πn + π}{2}

= sin (\frac{2 πn + π}{2})

2 (5 - 1)

\frac{1}{25} (e^{5 x} \cdot 5 x - e^{5 x})

(22 + 2) i

\frac{d}{d s} ((x (s, t)) (s + t))

(7 cos (x) + 1)^{2}
