Verify the Identity sin(6x)=2sin(3x)cos(3x)
Problem
Solution
Identify the double angle formula for sine, which states
sin(2*θ)=2*sin(θ)*cos(θ) Substitute the value
θ=3*x into the double angle formula.Observe that
2*θ=2*(3*x)=6*x Rewrite the left side of the identity using the substitution to show it matches the right side.
