Step-by-step explanation:
This an answer see in picture
You are given 2cos² (4θ - 1). You are asked to s<span>implify the expression by using a double-angle formula.
Apply the double angle of the cosine function
</span>cos2θ = 2cos² θ - 1
Rearranging the expression and then substituting them
2cos² θ = cos2θ + 1
2cos² (4θ - 1) = cos 2(4θ - 1) + 1
cos2(4θ - 1) + 1
