derivative y=e^{2-x}

解答

导数

y = e^{2 - x}

- e^{2 - x}

求解步骤

\frac{d}{d x} (e^{2 - x})

使用连锁律:

e^{2 - x} \frac{d}{d x} (2 - x)

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

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

= e^{2 - x} (- 1)

化简

= - e^{2 - x}

\int_{0}^{3} (9 - x^{2}) d x

\frac{d}{d a} (\frac{tan ^{2} ( a ) - sin ^{2} ( a )}{tan ^{2} ( a )})

\frac{d}{d x} (8 x y - \frac{1}{4} (x + y)^{4})

f (x) = x^{2} cos (x^{2})

\int \frac{ln ( x ^{3} )}{x} d x
