d/(dt)((x)(x^2+y^2))

解答

\frac{d}{d t} ((x) (x^{2} + y^{2}))

0

求解步骤

\frac{d}{d t} ((x) (x^{2} + y^{2}))

将

x, y

视为常数

常数微分:

\frac{d}{d x} (a) = 0

= 0

e x p an d (x + 1) (x - 1)^{5}

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

e x p an d \frac{( 2 s ^{3} - s ^{2} )}{( 4 s ^{2} - 4 s + 5 ) ^{2}}

e x p an d (1 - \frac{x}{4})^{10}

e x p an d (6 - 2 x^{\frac{1}{2}})^{2}
