Q:
# Pi/24 is the solution for 4cos2 (4x) - 3 = 0True or false

Accepted Solution

A:

Answer:True.Step-by-step explanation:Given, 4cos2 (4x) - 3 = 0Now, 4π/24 = π/6
Or, cos π/6 = √3/2Or, cos^2 π/6 = 3/4Or, 4 cos^2 π/6 = 3Now, Left Hand Side= 4cos2 (4x) - 3 = 3-3 =0 = Right Hand Side (Proved)Here, Left Hand Side= Right Hanad Side. So, 4cos2 (4x) - 3=0 is true.
