(\partial)/(\partial x)(sin(3x))

解答

\frac{\partial}{\partial x} (sin (3 x))

解答

cos (3 x) \cdot 3

求解步骤

\frac{\partial}{\partial x} (sin (3 x))

使用连锁律:

cos (3 x) \frac{\partial}{\partial x} (3 x)

= cos (3 x) \frac{\partial}{\partial x} (3 x)

\frac{\partial}{\partial x} (3 x) = 3

= cos (3 x) \cdot 3
