integral from 0 to 1 of cos(θ)

解答

\int_{0}^{1} cos (θ) d θ

sin (1)

十进制

0.84147 \dots

求解步骤

\int_{0}^{1} cos (θ) d θ

使用积分常见定则:

\int cos (θ) d θ = sin (θ)

= [sin (θ)]_{0}^{1}

带入上下限计算后得:

sin (1)

= sin (1)

\int_{0}^{\infty} 4 x d x

\int_{2}^{3} e^{t} d t

\int_{0}^{1} (- y - \frac{1}{2} e^{y}) d y

\int_{- 1}^{3} 1 + (2 y + 3)^{2} d y

\int_{0}^{b} (a - a \frac{x}{b}) d x
