For math, science, nutrition, history Cos2x is a double angle trigonometry that has the espansion of cos2x = cos^2 (x) -sin^2 (x) but you know that sin^2 (x) + cos^2 (x) = 1. making sin^2 (x) the subject of the formula of the latter formula gives sin^2 (x) = 1 - cos^2 (x), substituting sin^2 (x) in the first equation gives cos2x = 2cos^2 (x) - 1 putting this value of cos2x … Formula. 1 + cos.

cos2x skulle jag hellre skriva som cos(2x), alltså Cosinus för dubbla vinkeln. Om x är pi/6 radianer (samma som 30 grader) 2cos(pi/3) = 2 sqrt(3)/2 = sqrt(3) cos(2*pi/6) = cos(pi/3) = 1/2 . Ta gärna för vana att alltid sätta en parentes runt funktionsvariabeln, alltså runt vinkeln: sin(v) och inte sinv.
