derivative of arccot(sqrt(2x))

解答

\frac{d}{d x} (arccot (2 x))

- \frac{1}{2 x ( 2 x + 1 )}

求解步骤

\frac{d}{d x} (arccot (2 x))

化简

arccot (2 x) : arccot (2 x)

= \frac{d}{d x} (arccot (2 x))

使用连锁律:

- \frac{1}{( 2 x ) ^{2} + 1} \frac{d}{d x} (2 x)

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

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

= - \frac{1}{( 2 x ) ^{2} + 1} \cdot \frac{1}{2 x}

化简

- \frac{1}{( 2 x ) ^{2} + 1} \cdot \frac{1}{2 x} : - \frac{1}{2 x ( 2 x + 1 )}

= - \frac{1}{2 x ( 2 x + 1 )}
