Cos2x sin2x 1 2sin2x identity
WebQuestion 615270: verify the identity tanx (1-sinx^2x)=1/2sin2x Answer by lwsshak3 (11628) ( Show Source ): You can put this solution on YOUR website! verify the identity tanx (1-sinx^2x)=1/2sin2x ** Start with left side tanx (1-sinx^2x) = (sinx/cosx) (cos^2x) =sinxcosx = (1/2)sin2x verified: left side=right side Websin 2 x + cos 2 x = 1 is basically just the Pythagorean identity ( a 2 + b 2 = c 2) expressed in Trigonometric terms instead of Algebraic terms. And that's important because the Pythagorean theorem is the basis for almost all trigonometry. – RBarryYoung Mar 21, 2014 at 16:57 Add a comment 2 Answers Sorted by: 11
