Web yes, cos 2 ( x) usually means cos ( x) ⋅ cos ( x). Web cos2x is an important trigonometric function that is used to find the value of the cosine function for the compound angle 2x. Web detailed step by step solution for cos(2x)=cos(x) frequently asked questions (faq) what is the general solution for cos(2x)=cos(x) ? Cos 2 x is probably most common as shortest ( cos ( x)) 2 is most clear. Cos(2x) = cos(x+x) = cosxcosx −sinxsinx = cos2x −sin2x = cos2x −(1−cos2x) = 2cos2 x−1 so, cos2x = 21+cos(2x) which can be substituted. 2cos2x − cosx − 1 = 0.
