This can be solved as follows:
Explanation:
Solution is
where
Explanation:
Using the identities
Muliplying both sides with
Setting both factors equal to zero
From (2), Due to sinusoidal nature of both
where
graph{y=sin x [-20, 20, -2, 2]}
Similarly from (3) we get
graph{y=cos x [-20, 20, -2, 2]}
From (4) and (5)
