For example: Given sinα = 3 5 and cosα = − 4 5, you could find sin2α by using the double angle identity. sin2α = 2sinαcosα. sin2α = 2(3 5)( − 4 5) = − 24 25. You could find cos2α by using any of: cos2α = cos2α −sin2α. cos2α = 1 −2sin2α. cos2α = 2cos2α − 1. WebJul 27, 2024 · 2cos2( x 2) = 10 7. cos2( x 2) = 5 7. cos( x 2) = ± √5 7. The domain was originally π 2 < x < π but since it is now x 2, the domain has changed to π 4 < x 2 < π 2 ie first quadrant only. Therefore, cos( x 2) = √5 7 only as cosine is positive in the first and fourth quadrant and negative in the second and third quadrant. x 2 = 0.56. teamwork panda
