WebGiven 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 In any case, you get cosα = 7 25. Jim H · 1 · Mar 6 2015 What are Double Angle Identities? WebNov 8, 2024 · 11/08/20. Stephen K. tutor. The easiest and simplistic way to do this ( my preferred method for doing any math problem) is to realize that tan (2u) = sin (2u)/cos (2u) These are values that we already have so tan (2u)= (-240/289)/ (161/289) = -240/161 That was easy and helps you avoid the calculation errors you made. garth lund flair airlines
