0:068:24How to Use the Double Angle Identities to Find Sin(2x) and Cos(2x)YouTubeStart of suggested clipEnd of suggested clipSo the two double angle identities that I’m going to use in this video are sine of 2x equals 2 sineMoreSo the two double angle identities that I’m going to use in this video are sine of 2x equals 2 sine of X times cosine of X and cosine 2x is equal to cosine squared X minus sine squared X for cosine 2x
Proving the Double Angle Trig Identities (sin2x=2sinxcosx)
Proving the double angle trig identities is made simple in this walkthrough of how to prove identities such as
Why does sin(2x) = 2sin(x)cos(x)
