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

expand

sin (\frac{π}{2} \cdot (x + 1))

cos (\frac{π x}{2})

Solution steps

sin (\frac{π}{2} (x + 1))

Expand

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

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

Rewrite using trig identities

= cos (\frac{π x}{2})

(x + 1) - 2 x

\frac{3 x ^{2}}{( 2 x - 9 ) ^{2}}

\frac{x ( l - x )}{l}

(x + 17) (\cdot + 7)

e^{2 (t + 1)}
