sin4x-cos4x=2sin2x-1 ..prove the following - Brainly.in

WebbAnswer (1 of 4): We work by using the identity: {cos(2x) = 2cos^{2}(x) - 1} Therefore, {cos(4x) = 2cos^{2}(2x) - 1} Adding 1 to both sides to the above equation, we’ve: {1 + cos(4x) = 2cos^{2}(2x)} -(i) So till now, we’ve worked out to simplify our Numerator :) Now for the Denominator part...
