expand 2sin(pi/2 (x-3))+6

expand

2 sin (\frac{π}{2} (x - 3)) + 6

2 cos (\frac{π x}{2}) + 6

Solution steps

2 sin (\frac{π}{2} (x - 3)) + 6

2 sin (\frac{π}{2} (x - 3)) = 2 cos (\frac{π x}{2})

= 2 cos (\frac{π x}{2}) + 6

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

\frac{2 x - 1}{( x - 4 ) ^{2}}

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

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