derivative sqrt(3+x)

解答

导数

3 + x

\frac{1}{2 3 + x}

求解步骤

\frac{d}{d x} (3 + x)

使用连锁律:

\frac{1}{2 3 + x} \frac{d}{d x} (3 + x)

= \frac{1}{2 3 + x} \frac{d}{d x} (3 + x)

\frac{d}{d x} (3 + x) = 1

= \frac{1}{2 3 + x} \cdot 1

化简

= \frac{1}{2 3 + x}

x \to + 0 + lim (ln (2 x))

\int_{1}^{2} \frac{x}{2} d x

\int t t^{2} + 2 d t

\int \frac{y}{x} d x

n = 2 \sum \infty \frac{n}{( n - 1 ) !}
