expand (38xy)/((x^2+y^2+1)^2)

expand

\frac{38 x y}{( x ^{2} + y ^{2} + 1 ) ^{2}}

\frac{38 x y}{2 x ^{2} y ^{2} + x ^{4} + 2 x ^{2} + y ^{4} + 2 y ^{2} + 1}

Solution steps

\frac{38 x y}{( x ^{2} + y ^{2} + 1 ) ^{2}}

(x^{2} + y^{2} + 1)^{2} = 2 x^{2} y^{2} + x^{4} + 2 x^{2} + y^{4} + 2 y^{2} + 1

= \frac{38 x y}{2 x ^{2} y ^{2} + x ^{4} + 2 x ^{2} + y ^{4} + 2 y ^{2} + 1}

e^{- 2 t} (- sin (4) 4) + cos (4 t) (e^{- 2 t} - 2 t)

\frac{d ^{3}}{d x ^{3}} ((y) (3 x^{3} + 6 x^{2} - 4 x))

\frac{2}{5 ( 10 s ^{2} + 7 s + 1 )}

7350 (z - e^{- T}) (z - e^{- 2 T}) (z - e^{- 7 T})

\frac{d}{d x} ((f (x)) (4 x^{3} - 4 x))
