Question

How can i solve integral parts

`integral of e ^2 sin(3)`
​

Answer 1

`f (e² sin (3))`

integrate it :

`→ (1)/(2 + 1) e²(-cos(3x))`

add constant:

`→\frac{ {e}^(2) }{3} cos(3x)+c`

Answer 2

`-(e^2)/(3) cos(3x) +c`

Step-by-step explanation:

• 
  `\int \left(e^2sin\left(3\right)\right)`

integrate it :

• 
  `(1)/(2+1)e^2 (- cos(3x))`

add constant:

• 
  `-(e^2)/(3) cos(3x) +c`
