Return the Euclidean norm, sqrt(sum(x**2 for x in coordinates)) . This is ... Return the sine of x radians. math.tan(x)¶. Return the tangent of x ... sin 2x = 2 sin x cos x; cos 2x = cos2 x - sin2 x (or) = 1 - 2 sin2x (or) = 2 cos2x - 1; tan 2x = 2 tan x / (1 - tan2x). If we replace x with A/2 on both sides ... ... 2 \tan(x)}{1 - \tan^2(x)}} tan(2x)=1−tan2(x)2tan(x)​. tan(2x) = [2 tan(x)] / [1 -.
