integral from 0 to x of 1/4

解答

\int_{0}^{x} \frac{1}{4} d x

\frac{x}{4}

求解步骤

\int_{0}^{x} \frac{1}{4} d x

常数积分:

\int a d x = a x

= [\frac{1}{4} x]_{0}^{x}

带入上下限计算后得:

\frac{1}{4} x

= \frac{1}{4} x

化简

= \frac{x}{4}

\int_{- x}^{x^{2}} (8 x - 10 y + 4) d x

\int_{- 7}^{- 3} - x^{2} - 3 x d x

\int_{- 5}^{- 4} 2 x + 3 d x

\int_{- π}^{π} 2 x^{4} d x

\int_{- 1}^{1} 4 x^{2} (- x^{3} - 1)^{3} d x
