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

expand

cos (\frac{π}{2} \cdot (x + 1))

- sin (\frac{π x}{2})

Solution steps

cos (\frac{π}{2} (x + 1))

Expand

\frac{π}{2} (x + 1) : \frac{π}{2} x + 1 \cdot \frac{π}{2}

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

Rewrite using trig identities

= - sin (\frac{π x}{2})

(e^{i wt} + e^{- i wt}) e^{- i wt}

\frac{7 ( a + h ) - 6}{( a + h ) - 8}

\frac{5 ( x + 2 )}{2 x - 14}

y (2 x + 3 y = - 2)

\frac{( 3 x + 1 ) ( 3 x - 1 )}{9}
