derivative y=x^{x^2}

解答

导数

y = x^{x^{2}}

x^{x^{2}} (2 x ln (x) + x)

求解步骤

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

使用指数法则:

a^{b} = e^{b l n (a)}

x^{x^{2}} = e^{x^{2} l n (x)}

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

使用连锁律:

e^{x^{2} l n (x)} \frac{d}{d x} (x^{2} ln (x))

= e^{x^{2} l n (x)} \frac{d}{d x} (x^{2} ln (x))

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

= e^{x^{2} l n (x)} (2 x ln (x) + x)

e^{x^{2} l n (x)} = x^{x^{2}}

= x^{x^{2}} (2 x ln (x) + x)

\frac{\partial}{\partial x} (- x cos (y))

\int 3 cos (x) - \frac{1}{x} d x

\int_{1}^{11} \frac{1}{x - 8} d x

\int_{- 2}^{2} \frac{10}{x ^{2} - 4 x - 21} d x

\int (3 sec (x) tan (x) - 5 csc^{2} (x)) d x
