Question

give me fast answer this question​

Answer 1

Answer:

it's zero, am I right bro

Answer 2

Answer:

integration of

$\sin( {}^{7} x) dx \: = 7 \sin(x) \cos( {}^{7}x )$

limit is 0 - π so

2 I =

$\pi \times 7 \sin(\pi) \cos( {}^{7}\pi )$

l =

$\pi \times 7 \sin(\pi) \cos( {}^{7}\pi ) \div 2$
