Hello student, Please find the answer to your question below
sin242-sin284
= (sin42-sin84)(sin42+sin84)
use the following formulas :-
SinC + SinD = 2Sin[(C+D)/2]Cos[(C-D)/2]
SinC - SinD = 2Cos[(C+D)/2]Sin[(C-D)/2]
sin242-sin284
= (sin42-sin84)(sin42+sin84)
use the following formulas :-
SinC + SinD = 2Sin[(C+D)/2]Cos[(C-D)/2]
SinC - SinD = 2Cos[(C+D)/2]Sin[(C-D)/2]
