integral from-2 to 2 of e^{cos(x)}sin(x)

解答

\int_{- 2}^{2} e^{c o s (x)} sin (x) d x

0

求解步骤

\int_{- 2}^{2} e^{c o s (x)} sin (x) d x

如果 f(x) 是奇函数，并且在区间:

[- a, a]

范围内连续，则

\int_{- a}^{a} f (x) d x = 0

e^{c o s (x)} sin (x)

的奇偶性:

奇

= 0

\int_{- \frac{π}{4}}^{- \frac{π}{6}} 2 cos (x) d x

\int_{- \infty}^{x} f (t) d t

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

\int_{- 1}^{1} 9 x^{5} - 3 d x

\int_{2}^{5} (y^{2} - \frac{1}{y ^{2}})^{2} d y
