WebAs cos2theta = cos^2 (theta) - sin^2 (theta) = 3/5, and sin^x + cos^x = 1, then cos2theta = 1 - 2sin^2 (theta) = 3/5 therefor sin^2 (theta) = (3/5 - 1) (-1/2) therefor sin (theta) = 1/sqrt (5) As sin^2 (theta) + cos^2 (theta) = 1 As cos^2 (theta) - sin^2 (theta) = 3/5, we have cos^2 (theta) - (1 - cos^2 (theta) ) = 3/5 WebIf 1+sin2θ=3sinθcosθ, then prove that tanθ=1 or 1/2.
