Cosx = root sign 3 / 3, X belongs to the set of [0,2 π] finding X Such as the title

Cosx = root sign 3 / 3, X belongs to the set of [0,2 π] finding X Such as the title


Make the cosine function image, x = arccos root sign 3 / 3, π + arccos root sign 3 / 3
M = {arccos radical 3 / 3, π + arccos radical 3 / 3}



The set composed of real numbers x, - x, X2, - 3x3 has the most elements______ One


∵ x2 = | x |, and - 3x3 = - x, so there are at most two elements in the set
