解答

展开

e x (x - π) (1 - x)

e x^{2} - e x^{3} - e π x + e π x^{2}

求解步骤

e x (x - π) (1 - x)

乘开

(x - π) (1 - x) : x - x^{2} - π + π x

= e x (x - x^{2} - π + π x)

乘开

e x (x - x^{2} - π + π x) : e x^{2} - e x^{3} - e π x + e π x^{2}

= e x^{2} - e x^{3} - e π x + e π x^{2}

e x p an d ln (5 \frac{yz}{x ^{6}})

e x p an d \frac{x ^{4} + 5 x ^{2} + 2}{x ^{2} ( x ^{2} + 1 ) ^{2}}

e x p an d \frac{( x - 18 )}{( x + 1 ) ( x - 5 )}

\frac{\partial}{\partial x} ((y) (3 x^{2} + y^{2})^{3})

e x p an d \frac{1 - x + 3}{( x + 2 ) ^{2}}
