expand sin(((2n-1)pix)/2)

expand

sin (\frac{( 2 n - 1 ) π x}{2})

sin (\frac{2 πn x - π x}{2})

Solution steps

sin (\frac{( 2 n - 1 ) π x}{2})

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

= sin (\frac{2 πn x - π x}{2})

(t - sin (t)) (3 + 3 sin (t))

(3 + x) (2 + x)

\frac{( x + 5 ) ( x - 2 )}{( 2 x - 1 ) ( x + 2 )}

- \frac{j}{9} (3 m + 72)

\frac{10 a ( 4 x + 9 )}{81 b x}
