Question

integration of e^x sin 2x cos x​

Answer 1

there is a rule to integrate the funtion . like e^x( f(x)+f'(x)). So the result will be e^xf(x)+c. Now in given equ^n cosx=(sinx)' . So ans will be e^x sinx+ c. Hope it will help.

Answer 2

Answer:

1 divide n multiply whole by 2 ...

now take 1by2 outside integration sign

use formula of 2 sinAcosB

Now use integration formula of uv=uv'-int(d\dx u * int v)

Step-by-step explanation:

hope it helped....all the very best
