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

expand

cos (\frac{( 2 n + 1 ) π}{2})

cos (\frac{2 πn + π}{2})

Solution steps

cos (\frac{( 2 n + 1 ) π}{2})

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

= cos (\frac{2 πn + π}{2})

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

\frac{2 x}{( x + 3 ) ( 3 x + 1 )}

\frac{d}{d x} ((x) (x^{2} - 7 x + 1)) - (2 x - 7) (x + 9)

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

(- e^{- x} sin (x) + e^{- x} cos (x))^{2}
