Webb8 apr. 2024 · This identity simplifies the given trigonometric expression by factorising it as product of two factors. So, we have, sin 4 x − cos 4 x. So, we have simplified the trigonometric expression a bit but it can be further simplified by using the double angle formula for cosine. Now, we know that cos ( 2 θ) = cos 2 θ − sin 2 θ.
