But here both A & B are same and therefore. If you don't have a reference handy, you can check the answers by choosing an x that is easy to work with. For instance, choose x=pi/2, so cos (x) = 0 and sin (x) = 1. cos (2x) = cos (pi) = -1. a. cos2x skulle jag hellre skriva som cos (2x), alltså Cosinus för dubbla vinkeln. Om x är pi/6 radianer (samma som 30 grader) 2*cos (pi/3) = 2 * sqrt (3)/2 = sqrt (3) cos (2*pi/6) = cos (pi/3) = 1/2.
