Question

plz do the Integration
just check the atachment​

Answer 1

Answer:

1/14 sin7x + 1/2 sinx +c

Step-by-step explanation:

from trigonomatric formula 2cosxcosy = cos(x+y) + cos(x-y)

cos3xcos4x becomes 1/2(2cos3xcos4x)

1/2(cos7x + cos x) now solve by yourself.

Answer 2

1/14 sin7x + 1/2 sinx +c

Step-by-step explanation:

from trigonomatric formula 2cosxcosy = cos(x+y) + cos(x-y)

cos3xcos4x becomes 1/2(2cos3xcos4x)

1/2(cos7x + cos x) PLZ SOLVE AFTER THESE
