integral from x^2 to sqrt(x of)1

解答

\int_{x^{2}}^{x} 1 d y

x - x^{2}

求解步骤

\int_{x^{2}}^{x} 1 d y

常数积分:

\int a d x = a x

= [1 \cdot y]_{x^{2}}^{x}

化简

= [y]_{x^{2}}^{x}

带入上下限计算后得:

x - x^{2}

= x - x^{2}

\int_{2}^{4} 7 x d x

\int_{\frac{1}{3}}^{3} 2 - \frac{2}{x ^{2}} d x

\int_{0}^{1} 8.2 x d x

\int_{\frac{π}{12}}^{\frac{π}{6}} cot (3 x) + csc (3 x) d x

\int_{4}^{9} \frac{1}{x} - 2 d x
