d/(dy)(sin(xy^2))

解答

\frac{d}{d y} (sin (x y^{2}))

cos (x y^{2}) \cdot 2 x y

求解步骤

\frac{d}{d y} (sin (x y^{2}))

将

x

视为常数

使用连锁律:

cos (x y^{2}) \frac{d}{d y} (x y^{2})

= cos (x y^{2}) \frac{d}{d y} (x y^{2})

\frac{d}{d y} (x y^{2}) = 2 x y

= cos (x y^{2}) \cdot 2 x y

\int 6 sin (2 x) + sec^{2} (x) d x

\int e^{13 x} (13) d x

\int 16 cos^{2} (t) d t

x \to 3 lim (\frac{x}{3 - x})

f (x) = 5 x - 3
