expand (2pis)/((s^2+pi^2)^2)

expand

\frac{2 π s}{( s ^{2} + π ^{2} ) ^{2}}

\frac{2 π s}{s ^{4} + 2 π ^{2} s ^{2} + π ^{4}}

Solution steps

\frac{2 π s}{( s ^{2} + π ^{2} ) ^{2}}

(s^{2} + π^{2})^{2} = s^{4} + 2 π^{2} s^{2} + π^{4}

= \frac{2 π s}{s ^{4} + 2 π ^{2} s ^{2} + π ^{4}}

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

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

(2 q + r)^{\frac{2}{3}}

2 sin (\frac{π}{3} (x - 4)) + 6

\frac{d}{d x} ((x - π) e^{x - π}) + sin (x)
