(4sin(x))^'

解答

(4 sin (x))^{^{'}}

4 cos (x)

求解步骤

(4 sin (x))^{'}

将常数提出:

(a \cdot f)^{'} = a \cdot f^{'}

= 4 (sin (x))^{^{'}}

使用常见微分定则:

(sin (x))^{'} = cos (x)

= 4 cos (x)

\int \frac{1}{49 e ^{- 9 x} + e ^{9 x}} d x

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

\int (x^{3} + 6 x)^{5} (6 x^{2} + 12) d x

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

\int_{0}^{4} (4 - t) t d t
