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

expand

cos (\frac{( 2 x + 1 ) π}{2})

cos (\frac{2 π x + π}{2})

Solution steps

cos (\frac{( 2 x + 1 ) π}{2})

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

= cos (\frac{2 π x + π}{2})

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

\frac{n ! ( n + 2 )}{( n + 1 )}

\frac{( x ( x - 10 ) )}{x + 13}

x - 6 \cdot 7 x^{2}

t er m s (4 + 7 a^{2})^{2}
