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? Webwhere e is the base of the natural logarithm, i is the imaginary unit, and cos and sin are the trigonometric functions cosine and sine respectively.

WebCos3x is an important identity in trigonometry which is used to determine the value of the cosine function for an angle that is thrice the measure of angle x. It can be expressed in terms of the cos x. The behavior of the function cos3x is similar to that of cos x. As the period of cos x is 2π, the period of cos3x is 2π/3, that is, the cycle of cos3x repeats …
