derivative y=sqrt(5-2t)

解答

导数

y = 5 - 2 t

- \frac{1}{5 - 2 t}

求解步骤

\frac{d}{d t} (5 - 2 t)

使用连锁律:

\frac{1}{2 5 - 2 t} \frac{d}{d t} (5 - 2 t)

= \frac{1}{2 5 - 2 t} \frac{d}{d t} (5 - 2 t)

\frac{d}{d t} (5 - 2 t) = - 2

= \frac{1}{2 5 - 2 t} (- 2)

化简

\frac{1}{2 5 - 2 t} (- 2) : - \frac{1}{5 - 2 t}

= - \frac{1}{5 - 2 t}

\int_{0}^{1} (x - 1)^{3} - (x - 1) d x

\int 2 - 1 (e - x + 2) d x

d er i v a t i v e f (x) = 3 + 2 x^{3}

\frac{\partial}{\partial x} (2^{4 x} + 4 x^{2})
