(\partial)/(\partial x)(10sin(x))

解答

\frac{\partial}{\partial x} (10 sin (x))

10 cos (x)

求解步骤

\frac{\partial}{\partial x} (10 sin (x))

将常数提出:

(a \cdot f)^{'} = a \cdot f^{'}

= 10 \frac{\partial}{\partial x} (sin (x))

使用常见微分定则:

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

= 10 cos (x)

\int \frac{2 sech ^{2} ( t )}{tanh ( t )} d t

n = 1 \sum \infty \frac{n}{4 ( n + 1 ) !}

d er i v a t i v e ln (\frac{x ^{2} ( x + 1 )}{x + 2})

\int \frac{5 + 4 x}{1 + x ^{2}} d x

\int e^{- \frac{x}{8}} d x
