sin 2x = 2 sin 2x.cos 3x where x is a member of [0 , 3.14]
Added by Juan Luis O.
Step 1
First, we can simplify the right-hand side of the equation using the identity sin 2θ = 2 sin θ cos θ: 2 sin 2x cos 3x = 2(2 sin x cos x)(4 cos^3 x - 3 cos x) = 8 sin x cos x cos^3 x - 6 sin x cos x = 2 sin 2x - 3 sin x cos x Now we can substitute this expression Show more…
