derivative of 1/(sec(x))

解答

\frac{d}{d x} (\frac{1}{sec ( x )})

- sin (x)

求解步骤

\frac{d}{d x} (\frac{1}{sec ( x )})

化简

\frac{1}{sec ( x )} : cos (x)

= \frac{d}{d x} (cos (x))

使用常见微分定则:

\frac{d}{d x} (cos (x)) = - sin (x)

= - sin (x)

\int \frac{1}{x 2 x} d x

\frac{d y}{d x} = \frac{8 x 4 - y ^{2}}{4 - y ^{2}}

\int \frac{1}{( 1 + sin ( x ) )} d x

a re a x^{2} - 4, - 2 x - 3, - 1, 0

\int (3 x - 2) \cdot e^{- x} d x
