please solve the 184 no q​

Answer 1

1
$1 + sin (\frac{ x }{4} + theta) + 2cos( \frac{x}{4} - theta$
$1 + (sin \frac{x}{4}cos \: theta \: + cos \frac{x}{4} sin \: theta) + (cos \frac{x}{4} cos \: theta \: - sin \frac{x}{4} sin \: theta$
by this process you can get it answer if you could not get then comment me I will send you a link related to this question. for now you can practise it
