integral from 0 to 0.1 of (sin(x))/x

解答

\int_{0}^{0.1} \frac{sin ( x )}{x} d x

Si (0.1)

求解步骤

\int_{0}^{0.1} \frac{sin ( x )}{x} d x

这是非初等函数积分:

\int \frac{sin ( x )}{x} d x = Si (x)

= [Si (x)]_{0}^{0.1}

带入上下限计算后得:

Si (0.1)

= Si (0.1)

\int_{0}^{t} 3 u e^{2 u} cos (u) d u

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

\int_{- 1}^{1} \frac{4}{1 + 16 t ^{2}} d t

\int_{2}^{3} \frac{x}{x ^{2} - 4} d x

\int_{0}^{3} - 4 x^{2} d x
