yey次方怎么积分?
2021-11-08

∫y/e^y dy

= ∫ye^(-y) dy

= -∫y d[e^(-y)]

= -ye^(-y) + ∫e^(-y) dy,分部积分法

= -ye^(-y) - e^(-y) + C

= -(y+1)e^(-y) + C

∫y/e^y dy

= ∫ye^(-y) dy

= -∫y d[e^(-y)]

= -ye^(-y) + ∫e^(-y) dy,分部积分法

= -ye^(-y) - e^(-y) + C

= -(y+1)e^(-y) + C

∫y/e^y dy

= ∫ye^(-y) dy

= -∫y d[e^(-y)]

= -ye^(-y) + ∫e^(-y) dy,分部积分法

= -ye^(-y) - e^(-y) + C

= -(y+1)e^(-y) + C

∫y/e^y dy

= ∫ye^(-y) dy

= -∫y d[e^(-y)]

= -ye^(-y) + ∫e^(-y) dy,分部积分法

= -ye^(-y) - e^(-y) + C

= -(y+1)e^(-y) + C
